It's graduation time for the A-List crew. That means lavish yacht parties, designer caps and gowns, and saying bye-bye to high school for good.

Despite the festivities, Anna isn't in a partying mood. Ben's been acting distant and she is worried. Maybe her father's hot tattooed intern, Caine Manning, will help cheer Anna up! Ever since her illicit kiss with Parker, Sam has been Eduardo-less and heartbroken. But hopefully Sam will use her brains and considerable means to get creative about winning Eduardo back. And infamous Cammie? She couldn't care less about graduation, not when she's so close to unraveling the mystery of her mother's death. She'll stop at nothing to find out the truth.
