Plot details
On a mission it discovers the "black box" recorder for the SS Valiant, a lost Earth starship. The 200-year-old recorder is barely functional, but indicates that the Valiant had been swept from its path by a "magnetic space storm".

It holds data about the last moments aboard the ship, and shows that the crew had been frantically searching for information about extra-sensory perception (ESP) in the ship's library computer.

The tape ends as the captain gives the order to self-destruct.

Kirk has to know what happened to the Valiant and set off in search, on route they encounter a strange barrier that effects the electrical systems on the ship, at the same time the navigator Gary Mitchell and ship's psychiatrist Dr. Elizabeth Dehner are both knocked unconscious.

When they awake their eyes glow silver, well Mitchell does first and they both have amazing telepathic and telekinetic powers, which he later uses to kill Helmsman Lee Kelso and takes Dr. Dehner as he escapes.

Eventually he is killed by Kirk on the planet Delta Vega, but in the process Mitchell kills Dr.Dehner first.
