Jackie Peters is Brooke Peters' cousin, a close friend to Michael Brody, who she falls in love with. She develops a passion for sailing, just like Michael. She gets panicky and hysterical in dangerous situations, like when she and her friends are attacked by a great white shark. After the shark kills and eats Marge, Jackie is truly scared of it. She is extremely relieved when the shark is killed. She and Sean are then picked up and brought over to Cable Junction, where the rest of Michael's friends are waiting, by Martin Brody.
