A film star's stand-in is murdered, and microfilm of North American early warning systems has been stolen. The film star, despite an aversion to travelling by sea, proceeds to Montreal on a luxury liner. In an attempt to find the microfilm Dr. King is assigned as her personal doctor, and Steed goes undercover as a steward.

All of the information on this episode so far has been user-submitted. This episode has not been released on video in North America yet, so I have not been able to view it.

Someone coughs off-camera while film actress Carla Berotti is playing the victim of strangulation. The same cough is heard during Dr. King’s first meeting with Marson, Carla’s bodyguard.

“Looks like death warmed up,” says the director, as the cameraman bumps into something and the picture blurs.

Two strange squeaks are heard during the initial meeting between Dr King and Carla in her cabin.

Just before Dr. King enters his cabin to meet Nicholson, someone drops something off camera.

The boom mike appears then disappears as Nicholson approaches Carla on deck; when Steed wakes Dr. King from his deckchair; and just after Steed has been kicked off the gantry ladder by a villain (this time it’s the shadow of the mike).

There are also a couple of dialogue gaffs.
