In a backwater corner of the South Pacific in 1938, a young American adventurer and his ragtag group of friends become involved in death-defying hi-jinx, transporting people-on-the-run in a well-worn Grumman Goose seaplane.

Two astronauts and a sympathetic chimp friend are fugitives in a future Earth dominated by a civilization of humanoid apes. Based on the 1968 Planet of the Apes film and its sequels, which were inspired by the novel of the same name by Pierre Boulle.
