While going through yet another painful divorce, uptight chiropractor Alan (Jon Cryer) reluctantly moves himself and his son, Jake (Angus T. Jones), in with his serially single brother, Charlie (Charlie Sheen), a hard-drinking, womanizing jingle writer who's living the bachelor's dream inside an oceanfront Malibu beach house. But as a newly formed, non-traditional family comprised of Two And A Half Men, the brothers can't help but clash over their glaring differences. In later seasons, Charlie's character dies (offscreen) and is replaced by Walden Schmidt (Ashton Kutcher), a heartbroken internet billionaire.
