Plot
It's spring break, and the Pretty Little Liars are trading in Rosewood for a cruise vacation. They want nothing more than to sail into the tropical sunset and leave their troubles behind for one blissful week. But where Emily, Aria, Spencer, and Hanna go, A goes, too. From scuba diving to tanning on the upper deck, A is there, soaking up all their new secrets.

Emily is smooching a stowaway. Aria's treasure-hunting partner is a little too interested in her booty. Spencer's going overboard trying to land a new boy. And a blast—or rather, a crash—from Hanna's past could mean rough waters ahead for everyone.

The liars better tighten their life jackets. A perfect storm is brewing, and if they aren't careful, A will bury them at sea...

It's revealed that Hanna had a car accident when she was driving a drunk girl named Madison home. She panicked as she couldn't afford anymore trouble so she called the girls to help her. They move Madison's unconscious body and flee before anyone sees them.

Months later they prepare for a school cruise they're all going on and they're still on the look out for A. Emily has told her parents about the baby and they stop speaking to her. Spencer takes a huge liking to Reefer the guy she met at Princeton. Aria and Noel maintain to patch up their relationship. Hanna now has Mike back but is she teased and ridiculed over the stalker incident.
