16 year old Joan Girardi is approached by someone claiming to be God. He gives her a mission, get a job. Will Girardi, Joan's dad and new chief of police for Arcadia, is trying to solve the case of a serial killer.

Joan gets a lesson in popularity when God tells her to try out for the cheerleading squad, and her efforts to impress two pom-pom girls pay off with an invite to hang out together outside of school. Meanwhile, Will's first case working with Det. Toni Williams involves an abandoned newborn left in a trash bin, presumably by a student from Arcadia High. Another story line has a classmate sensing a gay vibe in Luke.

Each of the Girardis deal with crises of varying seriousness, the worst of which puts Will at the mercy of a crazed gunman. The day also finds Helen reacting with mixed emotions after getting a positive result on a home-pregnancy test. Meanwhile, Joan dreads having to take her driver's exam, and Luke is presented with a major distraction just before he's supposed to compete in a high-stakes competition.
