Frank Morris, Allen West, Clarence Anglin, and John Anglin all arrive at Alcatraz, all wanting escape from the moment they got there.
They start to dig holes in their prison cell walls, using spoons, nail clippers, and barricading it with fake carboard walls.
The four men create a makeshift work area, where they work together to formulate plans, build makeshift rafts, dummies, etc..
We can make rafts from these waterproof raincoats!
The men escape Alcatraz through the pipes. They get to the roof, but they have to leave John Allen Kendrick behind. They disappear into the nighttime.
Dummy heads are placed in their beds to deter guards. They leave with their rafts.
I won't be able to make it...
The men are never found. However, a body was found floating in the area. A raft was also found. The FBI claims that the three men died, but there is no evidence. The floating body was never identified.
