Plot summary

Professor Bernard Quatermass is in charge of a manned rocket mission that has gone awry. They lost contact with the spaceship at one point and have no idea how far into space it may have traveled. When the rocket crash lands in a farmer's field they find that only one of the three occupants, Victor Carroon, is on board; the others have simply vanished. Slowly, the surviving astronaut begins to transform into a hideous creature and Quatermass realizes that Carroon may have been infected by an alien being. When Carroon escapes from the hospital with the help of his unsuspecting wife, the authorities race to destroy it before it multiplies.—garykmcd
