Incensed that Will and Helen have forbidden her to go to a concert with Adam and stay overnight with him in his father's camper, Joan goes anyway.
After Joan has a conversation with God about free will, she decides to use it as a rationale for lying to her mother in order to go on the trip as she's convinced that Helen simply wants her to remain a dependent little girl. Meanwhile, Luke is shocked when the nerdy, girl-obsessed Friedman rebuffs the advances of the surprisingly infatuated Stevie.
A drama about a typical family, the Girardis, facing atypical situations - not the least of which is their teenage daughter Joan's sudden, unexpected conversations with God in such random forms as a cute boy, Goth kid, little girl or the school lunch lady. Joan (Amber Tamblyn) must endeavour to balance the natural and supernatural elements of her life, often with little success. This is not the only major problem the family must face as her elder brother Kevin (Jason Ritter) was paralysed from the waist down in a car accident in 2002. As a result, her younger brother Luke (Michael Welch) often feels that his needs are being ignored.
