In this episode, Mulder and Scully investigate the death of a federal construction worker and the destruction of various property that can only be tied to an escaped elephant. Unfortunately, the only witnesses claim to have seen no animals which might have caused the turmoil. Soon, Mulder and Scully discover the local zoo whose claim to fame is that they've never had a successful animal birth.
