Jim Fowler and Peter Gros have a stimulating African adventure on the Zambezi River where it thunders over the famed Victoria Falls. From the base they float downstream in rubber boats thru the great Batoka Gorge and on to Songwe. At last they reach Lake Kariba where they join members of the Zimbabwe Game Department in a project to capture and relocate elephants to establish new herds in areas where elephants once lived but have been exterminated.
