Sanger Rainsford and his hunting partner Whitney are traveling on the river to hunt the legendary giant cat of that region, the jaguar.
Rainsford listens to cannon shots, loses his pipe and when trying to recover it falls out of his boat in the Caribbean sea and swim to an island where he meets Zaroff (the general).
He decided to live on an island where he could capture shipwrecked and send them to the jungle to turn them into their prey.
Reinsford manages to wound the general on one shoulder, to scape the general, Rainsford throws himself off a cliff.
Zaroff believes that Rainsford has committed suicide and returns home.
