Transamerica

In about a week's time, pre-operative transsexual Bree will undergo the final operation that will complete her transition from a man to a woman. Just at this critical time, she learns that she has a son named Toby, and he is in trouble. Going all the way to New York, Bree bails Toby and the two of them set off on a trip back to Los Angeles, without Toby realising that Bree is his biological father.
