The 5th Monkey is a 1990 drama film directed and written by Éric Rochat and starring Ben Kingsley.

Cunda (Kingsley) lives deep in the Brazilian rainforest and is intent on making enough money so he can marry a widow in his village.

However, his trade - capturing snakes for scientists - pays very little money, and he is in direct competition with other suitors.

Recovered, he returns home and finds the four chimpanzees waiting for him, and his efforts to shoo them away fail.

Cunda now has to solve these two problems, and deal with the fact of the village woman's attraction to him plus his growing fondness for the chimpanzees he holds captive.
