Steven Callahan departs from El Hierro in the Canary Islands, in Napoleon Solo - a sloop he designed and built himself. He's bound for Antigua as part of the Mini Transat 6.50 single-handed sailing race from Penzance, England. One night a ferocious storm severely damages his boat. He escapes the sinking vessel in an inflatable life-raft, nicknamed Ducky, with a meagre supply of food and water. For 76 days he is adrift in the Atlantic Ocean at the mercy of the currents and winds. During his ordeal he is battered by the elements, attacked by sharks and plagued by constant punctures to his raft. It's an epic story where one man's will to survive is put to the ultimate test.
