Seven of Nine's discovery of a tenuous link to the Federation excites Capt. Janeway. When the normal method for sending messages proves inadequate, sending the Doctor, as a hologram, might work. The Doctor beams over to the Prometheus, a prototype starship ruthlessly captured by Romulans. The Doctor finds an ally in the ship's EMH, also a new prototype, but one who looks with disdain upon the earlier EMH model.
