Star Trek: The Mirror Frontier (2017)

This Star Trek fan-film explores Captain James T. Kirk and his crew which he doesn't recall being assigned to him and Captain Spock. The new crew members include Lt. Data, Tactical Officer Sulu, Cmdr. Uhura and Dr. Bashir for Transportation. What is everyone's real rank? Why are they really here? What is happening to corrupt the Enterprise from within? Or is Capt. Kirk simply losing his mind like he's been known to do from time to time?
