Trailer
In the fifth season, everything seems to be moving as Voyager investigates the birth of a mist. Unfortunately, after the mission's shuttle was caught away in the explosion, a transport accident during the team evacuation caused the doctor's mobile phone to be infected with the seven nanomaterials. The mobile emitter begins to absorb the science laboratory and creates a new unmanned aerial vehicle based on 19th century technology.
