An FBI agent infiltrates a gang of surfers suspected of being high-adrenaline bank robbers. Fresh out of the academy, the young agent must blend into the carefree world of surfing to uncover the culprits behind a string of sophisticated bank heists. Known as the "Ex-Presidents," the thieves wear masks of former U.S. leaders while committing their crimes, armed and evasively efficient. The agent soon becomes a skilled surfer under the guidance of a charismatic surfer guru with a philosophical bent and a daring approach to life.

As the agent delves deeper into the surfers' world, his loyalties begin to waver. His growing respect and friendship for the group's leader challenge his dedication to his job and blur the lines between duty and desire. In the process of unmasking the bank robbers, he encounters an unexpected kinship with the thrill-seeking lifestyle, which threatens to derail his mission and his principles. Balancing his undercover identity with the increasing risks of exposure, he races against the clock to gather evidence before his cover is blown or his newfound comrades are tipped off to his true intentions.
