The first manned spacecraft, fired from an English launchpad, is first lost from radar, then roars back to Earth and crashes in a farmer's field, and is found to contain only one of the three men who took off in it; and he is unable to talk but appears to be undergoing a torturous physical and mental metamorphosis.
Unfortunately the movie The Quatermass Xperiment is not yet available on Disney Plus.
