Amiable Mark Stevens and scientific partner, the enigmatic Marianne Koch combine to tackle malignant diseases through cryogenics, but their experiments on apes are just a prelude to their ultimate test on a live human being which Stevens himself undertakes shortly following a murder in which he's implicated in absentia. Koch attempts to resuscitate Stevens to answer the allegations under the watchful eye of a Detective (Lukschy) and an independent observer (Lohde), concerned she may sabotage the experiment to protect Stevens from punishment.
Capable German-US-British cast deliver realistic dialogue and create a genuine tension that is based less upon the primary plot (cryogenics) and more on Delphi Lawrence's character as Steven's almost perpetually inebriated wife, jealous of his working relationship with Koch, seeking solace in the scotch bottle and that of her old flame and work mate Joachim Hansen. Lawrence's performance dares to be bold and obnoxious, and while sometimes intense, doesn't become melodramatic. I thought her performance injected a maturity that was a welcome diversion to what could have become a simple science experiment gone awry picture.
While the momentum is not always fluent, the pace sometimes stilted, and the suspense often telegraphed too early, the acting compensates to some degree, Stevens and Koch enjoying a on-screen rapport that serves the narrative well. My only significant criticism is the overly-simplistic conclusion - the elements are present for a firecracker ending, but it's resolved too quickly and conveniently to do the rest of the movie justice. Should have been better, but in my opinion still superior to the average 3 rating it currently attracts.
