Keep the Lights On chronicles an emotionally and sexually charged journey of two men in New York City through love, friendship, and addiction. Documentary filmmaker Erik (Thure Lindhardt) and closeted lawyer Paul (Zachary Booth, Damages) meet through a casual encounter, but soon find a deeper connection and become a couple. Individually and together, they are risk takers – compulsive, and fueled by drugs and sex. In an almost decade-long relationship defined by highs, lows, and dysfunctional patterns, Erik struggles to negotiate his own boundaries and dignity while being true to himself.
