Welcome to The Three Captains. A charming bijou guesthouse on the Maine coast which is a haven of calm for guests and owners alike. When Lolly summons home her nieces, Isabel and June - one recovering from a broken heart, the other struggling to bring up her young son singlehandedly - they assume she's going to sell The 3 Cs, the place they called home after they lost their parents in a car accident. But the truth is much more heartbreaking than that.

Along with Lolly's daughter Kat - also at a crossroads in her life - the women spend their first summer together in years and home truths and long-buried secrets begin to emerge. Then movie buff Lolly invites her three offspring to attend her legendary movie nights and what at first seems like a few hours of distraction from their tumultuous lives becomes so much more. What they discover shakes them to the core, brings them together after years of discord, and provides them with the inspiration that they need to truly connect with each other and find happiness.
