In the aftermath of the Second World War, the island of Tinian served as the top-secret launchpad for the atomic bombs that changed the course of history. Decades later, a team of explorers and a former nuclear physicist return to the island to search for the remnants of the weapons that ended the war. As they scour the land and the surrounding waters, they uncover a landscape still littered with the dangerous, unexploded ordnance of a bygone era, forcing them to confront the physical and historical weight of the atomic age.
