julie and george find an article mentioning susie's father, ben willis (muse watson), and realise that ben was the man they ran over, moments after he had killed david to avenge his daughter. she and george then go to the docks to tell ray, but he refuses to believe them. julie and george notice ray's boat is called billy blue and run away. ben appears, knocking ray unconscious, and invites both julie and george to hide on his boat. on the boat, they find photos and articles about their friends and them, and pictures of susie. ben's boat leaves the docks, and he begins tormenting julie and george, chasing them below deck; there, they uncover the bodies of helen, charlotte and barry in the boat's ice box. ray regains consciousness and steals a motorboat to rescue julie and george. he ultimately uses the rigging to sever ben's hand and send him overboard. when the police question them, they deny knowing why ben attempted to kill them, but they are relieved not to have actually killed anybody the previous summer, and reconcile.
