For Love tells the story of Lottie Gardner, her brother Cameron, and their childhood friend Elizabeth, who all come together one summer in their hometown of Cambridge, Massachusetts, after years of separation. The packing up of her mother's house and the rekindling of the romance between Cameron and Elizabeth lead Lottie to look back at her past, as well as to consider the future of her own new marriage. The intrusion of a senseless tragedy upon the lives of all three characters forces Lottie to examine the consequences of the things she herself has done, and will do, for love.
