One Week (Spirk)
Spock and Jim have beamed down to a deserted planet to gather a crystal (which has hallucinatory effects, making you have vivid flashbacks to traumatic events in your past). On their way back to the ship, they find out the transporter is broken and their radios are being messed up from the everlasting storm that circles the planet. They have to make do for week with only themselves and their tragic pasts.
