A team of soldiers break into an enemy missile base. Such is the secrecy of their mission, they have been hypnotically programmed with their orders and will only remember each stage of the operation when they hear a pre-arranged signal. It seems foolproof, but gradually doubt and paranoia begin to overtake them.

The vengeful spirit of a dead motorcyclist is reluctant to leave his wrecked machine and manifests itself to a woman journalist as motorbike noise.
