Benjamin Bratt as William Banks, a recovering addict who helps others get clean by any means necessary as he struggles to maintain his own rocky personal life. William works with an eclectic team. Swenton is a wily smart aleck who is great undercover and always jealous of Akani, the beautiful, manipulative, and mysterious woman who always seems to get the best assignments and might just have a romantic past with William. Darnell is the newest member of William's crew. Darnell is deeply indebted to William for helping his younger brother get clean, but he must balance his deep religious convictions with the kind of work required as part of William's team.

Together with this eclectic group, William works week-in and week-out to bring addicts of all kinds to the point where they are ready and willing to get help and begin the difficult process of getting clean. With every success and every failure, William wrestles with his own demons through an unusual relationship with God. He's a man caught between an unwavering commitment to his work, deep love for his family, and the ghosts of his own addictions. Bad for his personal life, perhaps, but these are the tensions that make William the one you want helping a troubled loved one, the one you trust to do whatever is necessary, the man you want by your side in your darkest hour. In the face of tragedy and addiction, William Banks will risk everything to be The Cleaner.
