The movie is noted for its scenic, on-location shooting in Kenya, highlighting the landscapes of Lake Naivasha and Amboseli National Park.

The story follows Joe Moses (Robert Mitchum), a rough, cynical con man, diamond smuggler, and patent-medicine hawker who is chased out of a village in French Equatorial Africa. Following his departure, he is found injured and unconscious in the river "bull-rushes" by Julie Anderson (Carroll Baker), the daughter of a local missionary.

The movie remains a notable example of mid-1960s adventure cinema, featuring a "reluctant hero" performance by Mitchum.
