Robinson Crusoe, Dan O'Herlihy, the third son of his parents with few prospects, goes to sea against his father's wishes. On a voyage from Brazil to Africa to purchase slaves, a storm forces him to abandon ship. He manages to swim to a deserted island somewhere in the Atlantic Ocean on September 30, 1659.
An abandoned ship turns up on an offshore rock, allowing Crusoe to salvage food, tools, firearms and other items before it sinks. He builds a life from scratch: he herds goats, hunts, makes clothes, and constructs a home, with only the company of a dog, Rex, and a cat, Sam, as his companions; he later captures a parrot which he names Paul and teaches it to speak. Crusoe lets Sam and her kittens run wild. When Rex dies of old age in 1673, Crusoe nearly goes insane from loneliness.
In 1677, Crusoe discovers that cannibals visit his island with their victims. The next time he spots them with his telescope, he sees a prisoner make a break for it, pursued by two cannibals. He knocks out one and shoots the other; when the first one regains consciousness, the escapee kills him with Crusoe's sword. Crusoe takes the man back to his stockade. He names him Friday (Friday, Jaime Fernández after the day of the week they met). Crusoe teaches him English and Western customs and turns Friday into a servant. Crusoe does not trust him at first, believing Friday to also be a cannibal who would kill him if given the chance. He builds a door to the cave in which he takes to sleeping. When Friday enters without permission late one night to sneak some tobacco, Crusoe puts leg irons on him. The next day, however, Crusoe relents and takes them off. He comes to trust his new companion completely.
In 1687, Friday saves Crusoe from a cannibal sneaking up behind him. Seeing a large group, they flee back to their stockade. The cannibals, however, are driven off by white men with guns. Captain Oberzo [Felipe de Alba] and his bosun [Chel López] are the victims of a mutiny; Crusoe and Friday rescue the men and get away undetected. Friday then goes to the leader of the mutiny, offering him a basket of fruit, but the mutineers are more interested in the necklace of gold coins (salvaged from Crusoe's ship) he is wearing. Friday leads the greedy men to the stockade. There, Crusoe, Friday, Oberzo, and the bosun capture them. Oberzo regains control of his ship. At Crusoe's suggestion, Oberzo allows the mutineers to remain on the island rather than being sent to the gallows. Crusoe leaves them his tools and instructions on how to survive.
Crusoe leaves for home with Friday, having spent 28 years, two months, and 19 days on the island.
