Three Survived

Tom Rand, a practical engineer, and two other men are the only survivors of a spaceship explosion. Marooned on a hostile planet, they are being held captive by a group of “aliens.” Their one slim chance of survival is to reach a rescue beacon placed on the planet years before by men from Earth.
Can the three survivors escape what seems like certain, immediate death? And if they do, can they make their way through a jungle filled with untold dangers and reach the beacon in time?
