Michael Buerk presents the dramatic true story of a three-man Hollywood film crew who found themselves fighting for their lives in the crater of an active Hawaiian volcano. The group were over the Pu'u O'o-Kilauea volcano, filming an aerial sequence for the thriller Sliver, when their helicopter developed engine trouble, forcing the pilot to crash-land on the floor of the crater just inches away from a pool of molten lava. For the first time, National Park Rangers had the task of rescuing people trapped inside a live volcano, not knowing if they were alive or dead.
