Outer Limits: Monster stars Nicole deBoer as the lab assistant - Rachel
Sanders - researching ways on finding uses for other energies.
She takes part in her own experiment and has to prevent a dangerous energy
based being from escaping and killing people. The story is packed full
of info-dumping, blackmail twists and character angst but the special effects
are quite good.
To give you a clue about the plot, it alludes to a similar idea used in
the movie Forbidden Planet.
