Spencer the monkey has disappeared from the Popetown Zoo, and the buildings of Popetown are falling apart. Sister Penelope, always after a popular story, has tricked Father Nicholas into joining her in the catacombs for an interview, and Father Nicholas passes the responsibility of puting the young Pope to bed over to Sister Marie. Pope fools Sister Marie into believing that the energy drink Purple Papal Bull is a bed-time drink, and he guzzles down the whole can - only to end up fizzing, belching and 'jet' propelling himself all over the place... and then the energy part kicks in, sending Pope into an even greater frenzy. Pope ends up burning off the energy in the catacombs, but sets off a ceiling collapse that traps Pope, Father Nicholas, Sister Penelope and Sister Marie, and it's up to the Cardinals to form a rescue team.
A group of disabled children are coming to meet the Pope and perform, but the Pope has gone missing (playing hide-and-seek too well). Father Nicholas, in desperation to keep the days activities running seeks out a Pope impersonator. This impersonator is an exact image of the Pope, but unlike the real Pope, who is a young child with a girlie voice, the impersonator is a Jewish man with a Brooklyn/Jew accent. To pull off the scheme, he must be seen but not heard.
The Cardinals are hoping to secure a 'sponsorship deal' with the pending visit of a head of state and his darling wife. Problem is, this head of state is a gun toting dictator, and his only interests are seeing that his wife is pleased, and killing people who displease his wife. Father Nicholas has been given the task of tidying up the Pope prior to their arrival. Pope however has been attempting a record-breaking stint of going unwashed for 3 months!
