Best friends since they were kids, Grayson, Mike, and Ian were hoping for another epic summer on "The Locks", filled with clambakes, bonfires, and late-night swims in the ocean. But that was before Ians dad never returned home from his last deployment. Before Mike had to take on more responsibility in order to help provide for his family. Before Graysons accident left him with an injured throwing arm and an uncertain future. Its clear this summer on the island is shaping up to be very different from those Grayson, Mike, and Ian had come to rely on. And when the sacred code of dating a friends sister or ex is broken, it will push their friendship to the absolute limit, testing their loyalties in a way that could either break them-or save them.
