To help save the life of a Vidiian dying from the Phage, the Doctor creates a holographic body in which to preserve her mind. For the nearly dead woman, it's the first time experiencing life without the disease in years; for the Doctor, there's heartache when his adaptive programming opens up to romance, corroding the barrier between doctor and patient. Meanwhile, Tom's growing insubordination lands him in the brig, and Jonas balks at Lorrum's order to sabotage the ship.
