Sam Loudermilk, a former music critic and a recovering alcoholic, is a substance abuse support group leader living in Seattle, who regularly doles out clever but acid-tongued critiques to his clients, his friends, and any random person he interacts with. Loudermilk, who does not have his life together in the way one might expect of a counselor, is somewhat nicer to the few people close to him, including his best friend and (usually) sober sponsor, Ben Burns, and his sponsee and unplanned roommate, Claire Wilkes.
