On Kirk's orders, Noel enters the facility's physical plant through a ventilation duct, and interrupts Kirk's next neutralizer session by shutting off power to the entire complex. Freed from the neutralizer, Kirk attacks Adams, leaving him alone and unconscious in the treatment room. A guard discovers Noel's sabotage, but she kicks him into the circuitry, electrocuting him. With the force field now off, Spock beams down to the planet, disables the force field, and restores power to the colony. This reactivates the neural neutralizer, which empties Adams' mind completely, killing him.
