Belief that strange things befall during a lunar eclipse takes hold of the Davenport household as Leo records the events. Initially excited over a lunar eclipse, Principal Perry's surprise intrusion (seeking shelter from aliens in their underground lab) puts the family's focus on the eclipse as a herald of dire events. In particular, Perry swears to a lunar invasion in the works. Stomach growls from the spaceman food prepared and eaten by Chase for their lunar eclipse party only convince Perry that alien babies are within, sending Chase running for his life, Perry running for a knife, and the rest running for Perry before she causes them more strife.
