THRESHOLD Episode 1 Part 1 "Trees Made Of Glass"

Worst case scenario expert, Dr. Caffrey, recruits a team of elite and slightly eccentric scientists to determine if an alien civilization has made first contact with the human race. Mysteries abound. Is the alien race trans-dimensional? Is it friendly or malevolent? If friendly, why did the crew members of the ship that encountered the alien kill each other? Is the strange helical symbol an attempt at communication? Are the aliens altering the DNA of human test subjects? And how are the odd dreams/nightmares everyone is having related?
