(Some Spoilers) Thrown out of the prestigious Vienna Medical Academy for his illegal experiments Dr. Peter Blood, Kieron Moore,is now back home in the lovely and scenic coastal town of Port Carron England to continue his work undercover and underground.

Using his fathers position as the town doctor Robert Blood, Ian Hunter Peter builds a laboratory in the deserted coal mines outside the town to do his business undisturbed. While vacationing in the South American jungles Peter discovered the drug Curare from the local native tribesmen and has been using it in his experiments in his theory of eternal life. A brilliant but arrogant student Peter felt that he's smarter then all the professors and teachers in the academy put together. Which lead to him being run out of town, Vienna, on a rail.

Still not learning his lesson Peter is back on the road to destruction with him kidnapping people in and around town and after knocking them out working them over, in his secret lab,by taking organs out of one and putting them in another to keep the one receiving the organ going until he needs a new transplant. Looking and acting normal on the outside the tall dark and handsome Peter attracts, his fathers Dr. Robert Blood's assistant, pretty nurse and recent widow Lnda Parker, Hazel Court,who at first falls in love with him.

Peter putting on an act that he's in love with Linda takes her to his secret lab in the coal mines to, what seems to me, knock her out put her under the paralyzing drug Curare. Peter then use her in his experiments of involuntary organ donations. Lucky for Linda Peter's mad scheme is interrupted by the local town hobo Tregaye, Fred Johnson, who unknowingly to himself, and Linda, saved her life by popping up just at the right time.

Actually the brilliant Peter didn't come across that smart at all in the movie with all his experiments falling flat on their faces. All of Peter's victims from mine inspector George Beale, Andy Alston, to the local town undertaker old man Morton, Gerald Lawson, to the before-mentioned hobo Tregaye didn't produce the results that he hoped for.

In the end Peter ended up being the victim of one of his experiments that went very wrong for him but just right for the town and people of Port Carron. That experiment finally put and end to his insane actions once in for all.

Six years before the world's first human heart transplant, Dr. Blood's Coffin saw Kieron Moore star as Dr. Peter Blood, a biochemist determined to bring a man back to life by giving him a new heart. Of course, this being a horror flick, Blood is seriously deranged, his procedure requiring the donor to be still alive while the transplant takes place.

In order to carry out his plans, Blood returns to his rural home village in Cornwall (where absolutely no-one has a West Country accent), and proceeds to drug and abduct locals, taking them down to the tunnels of a nearby disused tin mine where he has set up a rudimentary operating theatre using medical supplies half-inched from the local surgery run by his unsuspecting father.

When he's not injecting victims with curare (which causes paralysis) and playing God in the mine, Peter spends his time wooing his father's curvaceous widowed nurse Linda (Hammer babe Hazel Court). As time goes on, Linda becomes suspicious of Peter, leading to a shocking climax that sees the demented doctor reanimating the nurse's decomposing husband.

While all of the above sounds like a lot of ghoulish fun, Dr. Blood's Coffin is less entertaining than it might have been, suffering from too many dialogue-heavy scenes and a lack of genuine horror, the only slightly disturbing scenes being the hasty removal of organs by a flustered Peter (he's a fast worker, completing the surgical procedure in minutes). The finale, in which Linda's mouldy husband comes back to life is incredibly silly, but easily the most enjoyable part of the film, director Sidney J. Furie finally delivering on the movie's macabre premise.

While there are some slow moments of this science fiction medical drama with a bit of a horror element, it is the type of film that begins to make you think as the ideals of the various people involved in the medical profession are revealed. Kieron Moore is seen at the opening of the film being terminated from a research hospital where he uses a live human as a part of his experiment. He returns to Cornwall, his home, reunited with father Ian Hunter and falling in love with nurse Hazel Court. Before he has made his grand return, people are missing from the village, and doctor Hunter and nurse Court are certain that something evil is afoot. Thanks to the caves on the coast, more is able to continue his experiments, but how long before his secrets come to light?

This is a great villain role for the handsome Moore, seemingly noble but secretly nefarious, breaking into a man's room in the middle of the night, chloroforming him and dragging him to the caves to perform his experiments. He even takes one of the local officials there in an effort to get suspicion off the caves, and the shot of one of the victims crawling around it's pretty shocking. As bodies begin to turn up, Moore begins to slip up, and there's a great confrontation between him and Court over the evils of scientists playing God.

The lack of blood and guts make this a non-traditional horror film, although there are some quick shots of body parts as more continues his bloody experiments. Veteran actor Hunter (a Hollywood leading man of the 1930's) is commanding as his very noble father, and Court is both beautiful and radiant as the nurse. She brings out what little humanity in Moore has left. Those expecting exploitive type science fiction and horror will be surely disappointed, but if you want something thought provoking and even spiritual, this one's for you.
