An eight-year-old boy is willing to do whatever it takes to end World War II so he can bring his father home. The story reveals the indescribable love a father has for his little boy and the love a son has for his father.

The series focuses on an eccentric motley crew that is the Smith family and their three housemates: Father, husband, and breadwinner Stan Smith; his better half housewife, Francine Smith; their college-aged daughter, Hayley Smith; and their high-school-aged son, Steve Smith. Outside of the Smith family, there are three additional main characters, including Hayley's boyfriend turned husband, Jeff Fischer; the family's man-in-a-goldfish-body pet, Klaus; and most notably the family's zany alien, Roger, who is "full of masquerades, brazenness, and shocking antics."

Zenon Kar is 15 and lives on a space station which the military has taken over and is dismantling. She receives a mysterious signal and must convince everyone that it's from aliens who have come to help them.
