Shore Leave

Captain Kirk orders shore leave for the Enterprise crew on a seemily unihabited planet in the Omicron Delta system. The landing parties begin to see strange sights, such as the White Rabbit, Don Juan, and a sword-wielding samurai. Kirk sees (and fights) an image of Finnegan, a rival from his Starfleet Academy days. Spock discovers that the planet seems to be drawing a large amount of energy from the ship's engines, placing the Enterprise in danger.[37]
