Page, a newly single, aspiring writer, moves into a new apartment, where her roommate, Modesty, rents out her room to a rotation of subletters. To cope with this intrusion of strangers, Page pretends to be a different person with each new tenant. One repeat subletter, a French filmmaker named Robert, takes an interest in Page and casts her in his film, and as Page’s acting career blossoms, she is forced to navigate the boundary between performance and reality.
