Halloween is long gone, but some people actually find it amusing to dress up. Dalia takes the opportunity to dress up as a hairstylist, Fotis dresses up as Sakis Rouvas and Thomas gets in touch with his inner nature, that of Superman. At the Van Reuben reception, Zoumboulia and Marilena realize that one of the bad guys is actually there and to make matters worse, a power outage and a bomb threat takes everyone to the garden (leading to some unfortunate reunions) but the presence of the police prevents any further agony. The five will once again get away, but upon ...

Which Pavlos is the real one, anyway? Fotis, Dalia and Aggela wait at Pavlos' home for Zoumboulia and Spyros (who were running late). Meanwhile, Spyros along with Sofia try to convince a police officer to spare Amalia (who has turned into a death - spreading driver), while Zoumbie is carried away by Marilena's second thoughts on her marriage to Thomas. Last but not least, Theopoula makes a new XXX Rated friend.

Two opposed sides. 5 hostages. The "good guys" treat their hostage as he deserves (Theopoula's fly-flap method) while the "bad guys" are trying to cope with their own hostages' demands. Soon, the two opposed sides will have to meet in international grounds and a hostage exchange, with unexpected results, will be arranged.

The 5 are in the police station, trying to persuade officer Tzoumanis that they really come from 5 different continents. When they finally get away with forgery, they decide that the situation calls for adult behavior and they organize a plan which involves Dalia being turned into the powerful business woman she has always hated being, Politis' telephone being bugged and two mysterious phone calls.

The 5 locate D.Politis' dad in a residential home. The two grannies take action and while Sofia is trying to gain Aristidis Politis' trust, Theopoula turns the elderly people's lives upside down with her revolutionary ideas. A.Politis finally decides to talk to grandma Sofia and Spiros but at the same time the team is taken aback by an unexpected visit from D. Politis.

The recorded revelations of his father have an immense effect on Dimosthenis Politis. Once the 5 manage to cope with this latest trouble, they send the tape and a Christmas card to the evil prime minister (signing as "5") and they decide to take a break. The rest of the episode is a Christmas fairy-tale which contains wishes, kisses and a miracle...

The new year finds our five heroes clueless. Being occupied with their personal problems (which vary from love-affair to job opportunities) they face the obligatory moving out from Fotis' apartment as the end of an era, considering that they ran out of "pieces" for the "jigsaw puzzle" they are trying to solve. Once, more the solution is given by Amalia who (while on a break from the making of her video clip "Fili fili me litronis", a song that contains the more "li" and "ni" possible) finds the right apartment for them!

"Noah 's Ark is invaded by Pirates" is the title of a fake children play but also the code name of Fotis and Aggela 's rescue plan. When the team finally manages to get out of the dangerous apartment, they decide to strike back, taking advantage of the fact that the bad guy doesn't know who his new neighbors are. Their new plan involves a misleading trip to Larisa and the installation of secret cameras to the bad guy s apartment.

The secret cameras get finally installed in the bad guy 's apartment but the team 's initial enthusiasm soon gives its place to disappointment, as they don't seem to find out anything interesting. However, an urgent call from the prime minister to the bad guy, leads the team outside the prime minister 's office, where they come across an unpleasant surprise. An invitation to dinner is the beginning of many important revelations to a familiar person who will either give them important clues or will lead them straight to jail.

Officer Tzoumanis is tied up in Dalia 's suite and forced by the 5 to hear their truth. When he manages to escape, threatening them with his gun, the 5 are in a state of panic and decide to leave the country for their safety. While going home to pack, Fotis and Aggela get captured by the bad guys. While the grandmothers are trying to persuade the group to choose Ibiza as a destination, a second visit from officer Tzoumanis makes them revise their plans and head for their next target: the 4th bad guy, a well-known lawyer.

Everything seems too good to be true with the 4th bad guy 's (Delikaris) case. Not only do they manage to talk to him, but he is willing to take Aggela (who pretends to have studied law) to do practice in his office. Alexis' decision to leave for Melbourne is final and Dalia gets very upset about that. In the meantime, Fotis comes up with a very interesting theory about the meaning of number "5".

Delikaris keeps playing "cat and mouse" with the five, constructing fake evidence for them to find in order to start trusting him. The five "pay a visit" to Delikaris' office and they soon find out that they re not the only ones to search among his documents. When Delikaris realizes that he is being chased by the Russian mafia, he changes his plans and decides to handle the five to the chief-bad guy (the prime minister) in exchange for his protection. In the nick of time, the five understand the trap that has been set to them and decide to take Delikaris aback by ...

The 5 are experiencing the most serious "defeat" in their secret agent history. Not only do they all suffer from multiple fractures and bruises (Aggela 's concussion has a very strange effect on her personality) but they also have to deal with the "restraining orders" they get from their terrified familiars. Even in that situation, the 5 can not stay away from "the case" as an innocent visit to the cinema leads them to new clues. Alexis is back from Melbourne but the motive of his comeback seems to be more serious than anyone can imagine.

Grandma Sofia and Theopoula 's visit to the supermarket has an unexpected turn. How will they take advantage of this event in order to get closer to the bad guys? At the same time, Alexis reveals the awful truth about Dalia 's father to the other four.

While the two grandmothers are about to retrieve some very helpful information about "the tall" bad guy, the four have to cope with the truth about Dalia 's father. Although the most seriously affected is Zouboulia, they all feel unable to be around Dalia and her "blood stained" money. Poor Dalia desperately needs an answer for the 4's attitude and they all have to make a choice between the significance of the "purple" and "yellow" papers that meant the death of their loved ones and the importance of friendship.

The bad guys get closer than ever to the actual identities of the 5, as they discover the address of Spiros but, at the same time, the 5 get hold of "the tall guy" 's personal details. They decide to pay a visit to the murdered girl 's sister, who gives them an archive identical to the one they lost (Stavrianidis' archive). Amalia is back, inviting them to her singing career debut and arranging a moving out which is going to save them once more in the nick of time.

Two telephone calls upset the team of 5: one is from Katerina Limnioti (Eleftheria 's sister) who tells them she might know the name of the fifth murderer and the other is from the chief-bad guy, the prime minister himself, who asks what it is that they want from him. Dalia and Alexis take part in a wedding rehearsal which is not (as they would both wish) their own. And just at the point where the prime minister believes he has cornered them, the 5 put their cards on the table showing him their real power.

Dalia 's visit to the prime minister has a remarkable impact on him, making him cancel his formal visit to the United States. This makes everyone worry, except from Dalia who is planning to turn their story into a James Ivory film or a musical or a science fiction porn. Aggela gets arrested and the four decide to make their final move, visiting the fifth murderer's house. But the bad guy is already there waiting for them.

"All good things come to an end" The 5 have finally completed the mystery puzzle they had been trying to solve for the past 2 years...they are in Dalia 's house filming a tape in order to reveal everything to the public and become very famous...or maybe not! Reaching the end of our story, we get to say goodbye to each of our heroes, by watching how each of them dealt with parting. As the story unfolds, we finally find out who Amalia, the mysterious girl who helped the team in the most critical moments and was the narrator of the whole story, really was. Now that ...
