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."

A dad finds out that parenting is harder than he thought after his wife goes back to work and he's left at home to take care of the kids.

A selfish postman and a reclusive toymaker form an unlikely friendship, delivering joy to a cold, dark town that desperately needs it.
