"The opening sequence of the game finds Larry mowing the lawn of Eve, his sexual encounter from the previous game, implying the pair have remained together. However, this is quickly revealed to be an instance of an unreliable narrator, as Eve pulls into the driveway with only the vaguest recollection of who Larry is. Realizing that his affair with Eve was merely a one-night stand, a distraught Larry wanders off, only to win a free vacation after stumbling into a rigged game show. During his preparations for the cruise, a microfilm falls into Larry's hands by mistake; this attracts the attention of the KGB as well as the mad scientist Dr. Nonookee (a pun on "no nookie"), who both want to recover the film."
