After their mother has a barely controlled freak out about their relationship, Billy and Billie both have a strange day that tests their loyalty to each other.
Billy & Billie centers on two young adults as they fall in love. They face the usual barrage of attention from their friends and family, and the normal anxieties that come at the start of a new relationship-all further complicated by the fact that they're stepbrother and sister.
