Steve is exposed to spores from a poisonous mushroom and becomes violently paranoid. Thinking the others are trying to turn him over to the S.I.D,. he lures them away one by one from the ship and ties them up inside a vent. Meanwhile, Inspector Kobick, fully knowing Steve has been exposed to the mushroom, expects him to turn on his friends.
