At the age of eight, Jaffy Brown encounters a tiger escaped from the menagerie of Charles Jamrach, wandering about London's East End. Taken up in the tiger's jaws, he is rescued by Jamrach himself, who then offers Jaffy a job. Jaffy loves working at the menagerie and becomes friends with another employee, Tim Linver. He falls in love with Tim's sister and the three of them grow up together on the streets of London. Several years later, when Jaffy is sixteen, he and Tim are dispatched by Jamrach to the Dutch East Indies, aboard a whaling ship. Under the charge of Jamrach's seasoned field agent, Dan Rymer, they have been sent to capture a "dragon" for the menagerie. The crew successfully capture the dragon, but on the return voyage it is set loose by Skip, one of the ship's mad crewmen, and after it bites a crew member they are forced to drive it overboard. Later the vessel is struck by a waterspout and sunk, leaving only a dozen men alive, stranded in the Pacific Ocean in two whaleboats. The two boats make for the coast of Chile, and as the crew gradually begin to die of starvation, thirst, sickness and exposure. Eventually only Jaffy, Tim, Skip and Dan are left alive, and they draw straws to see who will be killed (shot) and who will shoot him. Tim draws the marked piece of paper, and Jaffy kills him, an act which will haunt him for the rest of his life. Eventually Skip also dies, and by the time Dan and Jaffy arrive in Chile they are half-dead with exhaustion and half-mad from grief and anguish. In the book's coda, Jaffy returns home, faces Tim's family, and goes through a long period of depression and ennui. He eventually returns to life as a sailor, and in his retirement constructs a bird menagerie of his own.
