In the dense rainforests of the Ivory Coast and Uganda, a young chimp named Oscar is born into a close-knit tribe of chimpanzees. The beginning of his life is filled with curiosity and learning as Oscar observes and imitates the behaviors of his mother, Isha, who provides his primary care and teaches him essential skills for survival. The tightly bonded community of chimpanzees, led by an alpha male named Freddy, forages for food, plays, and deals with the daily challenges of jungle life. The social structure within the group is complex and intricate, with each member playing a vital role. Oscar rapidly learns from his mother and other group members, reveling in the playful side of his early days.

Oscar’s life takes a dramatic turn when a rival band of chimpanzees threatens his group, resulting in a fierce battle that disrupts their peaceful existence. Suddenly finding himself separated from his mother, Oscar faces the real and harrowing struggle for survival on his own. As he embarks on this challenging journey, he tries to integrate back into the group and navigate the treacherous environment of the jungle, which tests his resilience and ability to adapt. The unfolding events present an intimate and poignant look at the fragile existence of these intelligent primates and the interconnectedness of their lives within the natural world.
