The Doctor's experiment with daydreaming gets out of control when an alien race compromises his program. The aliens bully passing ships for supplies but, before doing so, first consult their command - The Hierarchy. One of the aliens, mistaking the daydreams for reality, gets permission to attack. Upon realizing his mistake, he offers to help Voyager but only if they act out one of The Doctor's fantasies, where he is in command of Voyager.
