Cinematic prequel to the 'Twin Peaks' television series, tracing the events leading up to the death of troubled teen Laura Palmer (Sheryl Lee). The saga begins when local police discover the corpse of a young woman named Teresa Banks. The FBI arrive to investigate and turn up a set of unusual circumstances, only to have two of their agents disappear without trace. Yet while the federal investigation continues under the leadership of the newly-assigned Agent Dale Cooper (Kyle MacLachlan), Banks' friend Laura Palmer sinks deeper and deeper into a personal hell involving nightmare visions, cocaine abuse and doomed relationships. Her friends Donna (Moira Kelly) and James (James Marshall) try to help, but nothing they do seems to be able to avert Laura from the bizarre, self-destructive path she is travelling.
