Meanwhile, the shark attacks the other kids, hitting one of their boats and causing most of them to capsize and crash into each other in the ensuing panic, throwing several of them, including Mike and Sean, in the water. The other teens help them out of the water while two of them pull Mike out as the shark goes for him and head back to get help. Sean and the others remain adrift on the wreckage of tangled boats. A Coast Guard marine helicopter that Brody contacted arrives to tow them to shore. Before the pilot can tow them, the shark attacks and sinks the chopper with the pilot at the controls. It then knocks Sean into the water, but Marge sacrifices herself to save him.
