Hot on the heels of Safari came another Columbia-released, African-filmed adventure, Beyond Mombassa. Matt Campbell (Cornel Wilde) arrives in Kenya on a double quest. He hopes to locate a valuable uranium mine, and also to learn the "whos, whats and whys" of his brother's murder. Joing Campbell's safari are missionary Ralph Hoyt (Leo Genn) and Hoyt's niece Ann Wilson (Donna Reed). After several attempts are made on Campbell's life, he comes to the conclusion that one of his travelling companions was responsible for his brother's death. Sure enough, the villain has not only dispatched Campbell's brother, but has also arranged the evidence so as to place the blame on a legendary tribe of "leopard men". As for why he does it, it is best to see Beyond Mombassa for further details.
