Les Stroud is shipwrecked on the desert island of Tiburon. Part of the Sonoran desert, Tiburon is searing hot in the day and freezing cold at night. The coastline is a barren stretch with no source of fresh water. Les must distill seawater and scavenge for clams and oysters amongst the rocks and mud to survive. With the threat of stingrays in the shallow waters and coyotes hunting the shoreline, Les battles hunger, fatigue and loneliness in this 10-day survival ordeal.
