When does jealousy betray forbidden love? Caitlin is spending a summer at a seaside cabin with her folks and her closest man Shaun. But when she witnesses him having his way with his girlfriend one night, in a romp behind a sand dune, she can't help but feel excruciating pangs of jealousy. Shaun finds Caitlin beautiful and funny, and he normally tells her everything. They've been close ever since they moved in together years ago. But ever since that one night, when he and his serious girlfriend Maya hooked up outside by the dunes, Caitlin has been acting a little strange. Not herself. And he's not sure what's wrong.... Caitlin needs to choose. Between making herself forget, or making a shocking taboo confession to Shaun, whatever the consequences might be. Which will it be?
