A new pair of best friends have their bond tested by their parents' battle over a dress shop lease.

After nearly four decades together, Ben (John Lithgow) and George (Alfred Molina) finally tie the knot in an idyllic wedding ceremony in lower Manhattan. But when George loses his job soon after, the couple must sell their apartment and - victims of the relentless New York City real estate market - temporarily live apart until they can find an affordable new home. While George moves in with two cops (Cheyenne Jackson and Manny Perez) who live down stairs, Ben lands in Brooklyn with his nephew (Darren Burrows), his wife (Marisa Tomei), and their temperamental teenage son (Charlie Tahan), with whom Ben shares a bunk bed. While struggling with the pain of separation, Ben and George are further challenged by the intergenerational tensions and capricious family dynamics of their new living arrangements.

It's 1997 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.

The late 1940s. Richard Langley, a bachelor playboy, narrates a story that starts when his best friend, Harry Allen, invites him to lunch to tell Richard he's in love. Trouble is, Harry's already married to Pat; he worries Pat would be hurt too deeply by a divorce. Then, Harry's new love, Kay, joins them. Richard is smitten, so when he finds out that Pat may be in love with someone else but won't tell Harry because she fears he would be too hurt, Richard can't decide if he should let all the cats out of the bag. He'd unite pairs of lovers, but he'd lose Kay. Meanwhile, Harry decides that a swift end to Pat's life would be more kind than divorcing her. He buys poison. Murder will out?
