Charlie (Charlie Sheen) is a well-to-do bachelor with a house at the beach, a Jaguar in the garage and an easy way with women. His casual Malibu lifestyle is interrupted when his tightly wound brother, Alan (Jon Cryer), who's facing a divorce, and Alan's son, Jake (Angus T. Jones), come to stay with him. Together, these two and a half men confront the challenges of growing up-finally. Complicating matters are the brothers' self-obsessed, controlling mother, Evelyn (Holland Taylor), and Alan's possibly gay estranged wife, Judith (Marin Hinkle). Not to forget Rose (Melanie Lynskey), a one night stand and current neighbor of Charlie's, who wants to be a part of his life and is willing to do anything to be around.
