Bree is a highly educated, conservative, transsexual woman who passes as a G.G. (a genetic girl), living in a poor section of Los Angeles and working two jobs to save money for her final sexual reassignment surgery. When she receives a phone call from Toby, a jailed teenage runaway looking for his father, she's shocked to discover that a heterosexual encounter during her life as a man resulted in a son. Bree wants no part of Toby, but her therapist insists she must confront her past, and withholds legal permission for Bree's final operation until she has met the boy. Bee grudgingly dips into her precious operation fund and flies to New York to bail Toby out of jail. Released to her without explanation, Toby assumes from Bree's conservative appearance that she's a Christian missionary who rescues street people and converts them to Jesus. Not ready for parenthood, Bree seizes her chance and encourages Toby's misconception. When she learns that the rebellious, disheveled Toby intends to skip bail and hitchhike to L.A. to break into X-rated videos and search for his real father, Bree panics. She doesn't want him to interfere with her plans for a safe, quiet new life. She offers him a ride cross-country, secretly plotting to abandon him with the stepfather he ran away from. As each lies to and manipulates the other, Bree and Toby find themselves on an unexpected and transformative journey.
