<p>Gemma had her summer all planned out, but it takes sharp turn when she gets dumped and finds herself back in the Hamptons after a five-year absence. Being there puts her at risk of bumping into Hallie, her former best friend (that is, before Gemma ruined her life) . But people don't hold grudges forever.
