Expelling the Demon (1999)

The story takes place in a bedroom where, following an embarrassing sexual encounter, it shows a naked man’s disaffection with his own tongue. Tongue being the articulator of the man’s voice, has been his lifetime proxy. But it is beginning to brazenly assert itself and fly in the face of its owner. The man can tolerate this no more and a power struggle ensues during which we learn something of the tongues dubious nature.
