6 swimmers from around the globe attempt to swim from Europe to Africa. A world champion swimmer, a CEO, a cancer patient, a heart attack survivor, an Olympian and a college professor whose lifelong dream has always been to swim the Strait of Gibraltar. Jetlagged, exhausted and somewhat underprepared, we follow the stories of these swimmers as they battle the freezing elements across two continents. Dodging huge shipping tankers while trying to reach unfriendly Moroccan border agents is just the beginning. This mental and physical “marathon in the dark” will test everyone with surprising results.
