The late Anthony Newley's star was already rising when he shared billing just after Robert Taylor and before Anne Aubrey in this fast-paced adventure story set in Africa. Adamson (Taylor) is an engineer in charge of a project to set up a railroad track through East Africa, the first of its kind -- well, almost. A rival railway gang is around to give him trouble. Aside from that kind of trouble, Adamson has to handle the convicts who are working underneath him, hungry crocodiles, dangerous lions, rhinos, and similar wild beasts, as well as Jane (Aubrey), a woman along for the duration. His sidekick Hooky (Newley) is a stand-out with his high energy brand of whimsy.
