An Irken masquerades as the new girl at school in order to settle an old score with Zim.
Dedicated Irken soldier Zim is sent on a secret mission to Earth, where he disguises himself as an elementary-school student and gathers information about human beings. His plan is moving smoothly until an extraterrestrial-obsessed classmate named Dib takes notice of Zim's green skin and missing ears.
After another day at the Earth skool, Ms. Bitters reminds the children that it’s Parent Teacher Night and that all the parents must come to the skool at the end of the day. Zim becomes worried because his robotic parents aren’t programmed for such a task yet and he cannot permit them to blow his cover, so he attempts to help them become the parents they should be, but Gir’s carefree nature soon puts his plans in jeopardy.
