In 1962, Frank Morris and brothers John and Clarence Anglin devised one of the most involved and innovative plans to escape Alcatraz, a prison on an island in the San Francisco Bay, known for housing some of the country's most dangerous criminals. Right under the noses of the guards they cut holes in their cell walls, crafted fake heads out of papier-mache as decoys, and constructed a raft out of raincoats, then successfully vanished one night. But after decades of false leads and dead ends, the fate of these escapees remains a mystery.
