Keep the Lights On chronicles an emotional and sexually charged journey between two men in New York City through love, friendship and addiction. Documentary filmmaker Erik and closeted lawyer Paul meet through a casual encounter, but soon find a deeper connection and become a couple. Individually and together, they are risk takers, compulsive and fuelled 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.
