A group of young adults spending a weekend together on a secluded island in Maine find themselves haunted by the choices they didn't make as they confront the meaning of love, friendship, and their lives in a world of virtual wonders and genetic cloning. Walt, a school teacher with a doting wife and two small girls, might seem to have it all. But when he meets Fiona, the lyrical world of his youth is reawakened, throwing into question the life he has chosen. Sensing trouble, his wife Rachel plans a romantic getaway weekend, but Walt has other ideas and invites his childhood friend Benjamin, a painter leading a cloistered existence in rural Vermont, for a rare visit. A run-in with friends sets in motion a chaotic weekend in which everyone must decide what they really want in life and what they're really willing to do to get it.
