It's a fast thriller constantly gaining speed, and it is not easy to follow all the sudden turns for good and for worse in this violent action stew of intrigue. A scientist is successfully smuggled out of East Germany and hidden in "a safe place" at the harbour of Hamburg, a very rugged place to my liking, from where an English skipper (Forrest Tucker) is paid handsomely to get him out of there over to England. The problem is there are others also interested in this case of an important Polish scientist with advanced knowledge of matters beyond anyone's conception. So there are some hunts both to save him and to get him, and when finally the guns come out to force the situation, Forrest Tucker begins to have had enough of fisticuffs and assaults and atrocities hounding him everywhere, while Eva Bartok in what must be regarded as one of her best roles actually finally saves the situation by her own bold initiatives and civil courage. It's a fast and entertaining film, Val Guest knew how to make such films of sustained action and suspense, and at least you will not be bored.
