One week before her vaginoplasty, a trans woman named Sabrina "Bree" Osbourne (Felicity Huffman) receives an unexpected phone call from a young man named Toby Wilkins (Kevin Zegers), a 17-year-old jailed in New York City. He asks for Stanley Schupak (Bree's deadname), claiming to be Stanley's son. Bree was previously unaware she had a son; she now wants to break with her past and renounce him. However, Bree's therapist (Elizabeth Peña) refuses to sign off for her operation if she does not face up to her past ties before facing her new future.
