THRESHOLD Episode 7 "Revelations"

Alien crystals have formed on a plank that showed up in the last episode and the team set out to find the wreck of the original ship to try and track the wreckage. What they find when they finally succeed is the stuff of nightmares for Caffrey. She, on the other hand, has problems of her own as she is licked up in cellar, beaten and bruised with a very dead body nearby.
