Desc: I diamanti rosa: With Enrico Fiori, Totò Majorana. Enrico Fiori, a sailor, finds himself on a raft, the only living survivor after a shipwreck, and after drifting several days without food or water, he at last comes upon a desert island, where he sustains himself by eating grass and drinking from a tiny stream. Wandering about the island one day, he discovers a cave in which he finds several skeletons, also a book that tells about a Spanish fort where some red diamonds are hidden. In order that he may be rescued from this island, he cuts his arm and writes a note for help with his blood, and throws it into the sea. A fisherman finds Enrico's note in the body of a fish and goes to his rescue. When they reach the island, they find him turned into a savage, who fights them, but they at last subdue him by smoking him out of a cave. Tying him up, they bring him back to civilization, put him into a hospital, where in time he recovers. On his recovery he tells the doctor and the nurse about the red diamonds and they both agree to start on a search with him for the diamonds. In the course of time they find the fort and secure the diamonds, which are given into the keeping of the doctor, who falls in with a gang of bandits. In order to escape he tells the bandits that Enrico Fiori and the nurse have the diamonds, and upon hearing this they let him go and start a search for Enrico and the nurse, whom they soon capture. The doctor, after escaping from the clutches of the bandits, meets a bear and in order to get away in a hurry, falls over a precipice. Meanwhile, the bandits not finding the jewels on Enrico and the nurse, tie them up and get drunk on the liquor they had stolen, and fall into a drunken sleep. While they are sleeping Enrico gets one of the robber's knives, frees the nurse and himself, lights a fuse that leads to a barrel of powder underneath the fort, and escapes while the robbers are blown up with the fort. As they are escaping they suddenly meet the doctor, who in order to right himself gives the diamonds to Enrico, but while they are sleeping he tries to steal the diamonds again. Enrico wakes up and struggles with the doctor, but is knocked unconscious with a limb of a tree. When Enrico gains consciousness he starts in search of the doctor and finds him near a stream. They again quarrel and in the excitement which follows both fall into the stream, where under water he takes the diamonds from the doctor and comes to the surface, while the doctor, who cannot swim, drowns. Enrico Fiori swims to the bank with the gems, climbs out and brings the nurse to the spot where the doctor had drowned.
