The second season of this comedy continues the story of Charlie Goodson (Charlie Sheen), a ballplayer-turned-therapist specializing in anger issues who also battles them himself. He's treating a group of regulars on a weekly basis and counseling prison inmates pro bono. Meanwhile, he's juggling complicated relationships with his ex-wife Jennifer (Shawnee Smith), and his best friend and sex buddy, Kate (Selma Blair). Sheen's real-life father Martin has a recurring role as Charlie's father, and Brian Austin Greene reprises his role of Sean. This season also features guest appearances by Cee Lo Green, Lindsay Lohan and Denise Richards.
