During the Oceans Seven extreme challenge, British marathon swimmer Beth French sets out to swim across 7 of the world's most dangerous sea-channels in one year. In an effort to set an example for her autistic son, Beth tackles jellyfish, sharks, nasty weather, hypothermia and her own demons as she journeys to the most remote parts of the world. As the story unfolds, Beth's desire to conquer the open sea comes into conflict with a mother's dreams for her son, resulting in an unpredictable and emotional climax.
