The Adventures of Captain Pels is about a family covertly defending a small beach town from a constant onslaught of pirate attacks. To all appearances, the family is simply enjoying a nice day on the beach - but the pirates may see through their disguise.

Each of the Pels children has a unique, hidden talent classified as "superhuman" by the secret agency tasked with thwarting the pirates. The children must tap into these skills to save their father... I mean Captain Pels. With determination, teamwork, and even empathy for their "enemies" this family is equal to the adventure's challenge.
