During a mining accident, the police arrest the sole survivor on suspicion of murder, whose pickaxe is stained with the blood of one of the victims. The investigation reveals that the identity card found on the victim belongs to another person, that the collapse was deliberate and that the miner believed to be the victim has escaped.
