Vic, an old adventurer, is commissioned by a mine owner to bring the legendary diamond "Mist of Namanga" to the diamond dealer Max. On the way, however, he is ambushed by gangsters and, in his distress, throws the suitcase with the valuable contents into the bush. To make matters worse, he runs into his ex-girlfriend Lisa, who is now engaged to the aforementioned Max - but has caught him with someone else and wants to leave him. In the excitement, however, she got on the wrong bus and now Vic and Lisa are on the run together, slowly getting closer again thanks to various adventures.
