Four Desperate Men on AllMovie

A daring escape from prison whips open this actioner right at the beginning, and though the action continues from that moment onward it does not sustain the same break-neck pace. Matt Kirk (Aldo Ray) is in jail, wrongly accused of a crime, and along with three other inmates he escapes by hiding out in an ambulance. Circumstances then lead Matt and the others to set off in a small boat that ends up drifting toward an island called Pinchgut in Sydney's harbor. As the fugitives hole up on the island, Matt devises a way to call attention to his demand for a retrial that instead calls attention to more police... and a siege of the island begins.
