Plot
Set in contemporary England, the film follows Doctor Brockton who learns that in the caves of the countryside, atroglodyte is alive and might be able to be helped and even domesticated. She gets the creature to the surface and attempts to train him, but runs into trouble as a few people oppose this, especially a local businessman afraid of negative commercial consequences, Sam Murdock. In the meantime, this creature, given the name of "Trog", has been given the power of speech, and has expressed some romantic feelings for the doctor's daughter, Anne Brockton. Murdock frees the creature, leading to a rampage. Trog is eventually cornered, with Anne's help, but chooses to die rather than be reduced to a zoo specimen.
