Submarine

Charlotte is an alcoholic trying to complete her first year of sobriety. One night, when the urge to drink is so strong that she fears a relapse, Charlotte decides to go see her chaperone, Jeanne, an alcoholic who has been sober for over five years. However, when Charlotte arrives at Jeanne's, she finds her chaperone in a state of drunkenness. With the roles of helper and cared-for now reversed, the stakes multiply for Charlotte when Jeanne's daughter Sarah arrives unexpectedly. As the traumas of her life with an alcoholic mother resurface, Charlotte decides to intervene with Jeanne and do everything in her power to prevent Sarah from suffering the same fate.
