Monkey Business Plot Summary

What happens in Monkey Business from start to finish, spoilers included, with a timeline of 15 key events. The opening is below; the full summary is a 3-minute read.

Spoilers ahead

Dr. Barnaby Fulton, Cary Grant, is a slightly absent-minded research chemist at the Oxly chemical company who dreams of an elixir of youth that could renew aging bodies. His boss, the financially shrewd Oliver Oxly, pushes him toward a breakthrough that could be a blockbuster, and the board shares the same keen interest in turning science into profit. The laboratory atmosphere buzzes with ambition, but chaos soon arrives in the form of Esther, a clever chimpanzee, who breaks loose and, in a moment of mischief, sprinkles a beaker’s contents into the water cooler. The mixture is not just a random accident — it holds the rejuvenating power Barnaby has been chasing.
