At the age of twenty-nine, Sydney has already been once divorced and once widowed. Trying to find her footing again, she has answered an advertisement to tutor the teenage daughter of a well-to-do couple as they spend a sultry summer in their oceanfront New Hampshire cottage. But when the Edwards' two grown sons, Ben and Jeff, arrive at the beach house, Sydney finds herself caught up in a destructive web of old tensions and bitter divisions. As the brothers vie for her affections, the fragile existence Sydney has rebuilt is threatened.
