Africa Love (1976)

Jack returns home to discover that his wife Jane has left. While the housemaid is having her way with a man, he overhears that she won't be back soon. Concerned, he heads to the bar he frequents and learns from the bartender that Jane departed for Africa with Danier, a friend of the bartender. Jack shows his intent to seek her there. The bartender convinces him to travel with seasoned swinger-type Anne who was born in Africa and is experienced in dealing with Africans.
