Joan of Arcadia - Season 2 - Eps 16: Independence Day
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.

Synopsis
Joan Girardi has begun acting a little strange since her family moved to the city of Arcadia. No one knows that various people keep introducing themselves as God, and then giving the teenager specific directions to do things. Unsure of what God wants, and if she's even sane, Joan tentatively begins to follow God's cryptic directives, all the while trying to retain a "normal" teen-aged existence.
