It's 1998 and New York City is in a state of intense flux when documentary filmmaker Erik Rothman (Thure Lindhardt) first meets Paul Lucy (Zachary Booth), a handsome but closeted lawyer in the publishing field. What begins as a highly charged first encounter soon becomes something much more, and a relationship quickly develops. As the two men start building a home and life together, each continues to privately battle their own compulsions and addictions. A film about sex, friendship, intimacy and most of all, love, Keep the Lights On takes an honest look at the nature of relationships in our times.
