A cocky, self-absorbed irresponsible person can become upstanding and generous. People, and chimps, can rise to the occasion. Science nerds can be cool. Being extra smart can help in difficult situations. The chimps use teamwork to find solutions to various problems.
An unmanned spacecraft looking for life crashes through a wormhole onto Malgor, the far-off planet with intelligent life in the form of odd-looking aliens. A nasty alien named Zartog learns to use the craft and its powers to dominate his people cruelly. He dips fellow citizens in a freezing solution called Freznard. A large volcano is about to blow throughout the action. Flesh-eating plants and animals threaten the chimps and others. Characters fall from high places. One of Ham's irresponsible stunts ends up knocking down four large rockets. Large birds catapult sharp spikes at people. A character appears to be dead but isn't. A monster appears to eat a character.
Astronaut chimp Ham is attracted to Luna, his female co-astronaut, and flirts obnoxiously with her. Even though she can't stand him, he asks, "What should we name our kids?"
