A story which on the face of it is proposterous (hospital porter impersonates a doctor after his sudden death) is done very well indeed thanks to the leading performance of Paul McGann.
Matthew, or Simon as he becomes as impersonator, turns from dreamer to avenger in this thriller as he seeks to protect and uncover his deception, assisted by friendly nurse Christine, played by Amanda Donohoe (remember how high her star was at this point?).
It's very dark and very persuasive, and if there are gaps in the narrative, this amoral leading character has enough to keep you gripped, and has much of the nervous, quiet energy McCann displayed in Withnail and I.
This film also displays the moral dilemmas faced by those who are embitious and in love; Christine displays classic accessory syndrome as she gets more involved in 'Simon's' deception and actions.
