Tim Fitzhigham meets the humans who defy science and puts their powers to the test - against himself. Tim meets Sara Campbell, a champion freediver. Do Sara's amazing underwater abilities make her a real-life Aqua Girl? Tim challenges Sara to three super tests in order to prove, or disprove, these gravity defying superhuman powers.

They travel to Dubai to go head to head in one of the world's largest aquariums and then onto the Gulf of Oman for the ultimate test in open water. These tests are extremely dangerous, so Tim uses state-of-the-art technology, real medical science and his very own mission doctor as he prepares for his challenges.
