Description: John Callahan (Joaquin Phoenix) has a lust for life, a talent for off-color jokes, and a drinking problem. When an all-night bender ends in a catastrophic car accident, the last thing he intends to do is give up drinking. But when he reluctantly enters treatment — with encouragement from his girlfriend (Rooney Mara) and a charismatic sponsor (Jonah Hill) — Callahan discovers a gift for drawing edgy, irreverent newspaper cartoons that develop an international following and grant him a new lease on life.
