Four greedy Ferengis have invaded Enterprise while the crew is unconscious. They have already confiscated numerous valuable supplies, but are still interested in more. They wake up captain Archer to get the know the whereabouts of 'the vault'. Another crew member is still awake in the decontamination chamber, Trip. He wakes T'Pol. Since the weakness of the invaders is not difficult to find, the three try to outsmart the Ferengis.
