First Con-tact
Summary
The crew responds to a distress signal that turns out to be Nandi, a Ferengi smuggler who raised Dal. Nandi has cloaking technology on her ship that can be powered by the chimerium crystals on the Protostar, and she offers to give the technology to the crew if they help her retrieve a remalite crystal from a nearby, unexplored planet. Janeway warns that interfering with the young civilization on that planet would violate Starfleet's Prime Directive, but her concerns are dismissed and the crew help Nandi steal the crystal. When they realize the damage that they have done, the crew steal the crystal back and return it to the planet, but Nandi escapes with their chimerium.
