The Big Gamble (1961)

Vic Brennan persuades his family to put up money for him and his wife to leave Dublin for the remote African town of Jebanda in order to start up a truck-hauling business. The family agrees to give Vic the money under the stipulation that his bumbling cousin Samuel goes with him to protect their investment. Their misadventures during their long trip along the Ivory Coast include a hijacking, catching a deadly fever, near drowning, thirsty natives and broken trucks.
