In this classic comedy from the 70s, we follow the hilarious misadventures of a chemistry student named Dexter, who accidentally creates a serum that grants superhuman strength. But here’s the twist: instead of using it to become a superhero or an athlete, Dexter decides to test his invention on Bonzo, his pet gorilla. When Bonzo transforms into a real muscle-bound powerhouse, chaos ensues.
Excited yet a bit out of control, Dexter realizes that his university work becomes much more complicated with a strong gorilla on the loose causing havoc. As he tries to recapture his furry friend, Dexter also faces academic pressure, skepticism from his professors, and rivalry from a competitor who wants to steal his invention.
Moreover, the young man must deal with his romantic interest, who sees him more as a madman than a genius. Amid this mix of entanglements, a strength competition turns out to be the perfect opportunity to showcase Bonzo’s true potential and Dexter's own ingenuity. What starts as an innocent experiment evolves into a hilarious series of situations where loyalty, friendship, and a bit of craziness come together to offer laughs and heartwarming moments. In the end, Dexter discovers that being the "strongest in the world" doesn’t always mean having colossal muscles, but rather having the courage and connection with those who care about you.
