Airplane engineers are being snatched off the street, so George Raft, an airplane designer, flies to London to take up Clifford Evans' job offer, only first he has to find him. This leads him to Sally Gray, who turns out to be working for British Intelligence. They start pursuing Evans together.
This is a rote movie and everyone seems to be putting in just enough energy to collect their paychecks. The script starts and stops for no clear reason, as bad guys try to kill Raft and then leave after the first attempt fails; a bad guy takes a swing at Raft, misses by several inches, and Raft falls down. The entire production is run in such a sloppy, uncaring manner that the viewer must be similarly unengaged.
There is some decent inadvertent documentary work in the site location; as Raft and Miss Gray wander about London, there are some nice views of still unrepaired war damage. However, given the generally low level of excellence, that made me think the film makers were ripping off shots from THE THIRD MAN and NAKED CITY.
This was Sally Gray's first movie since 1949 and her last. She would retire from the movies to become Baroness Oranmore and Browne, Baroness Mereworth in a fifty-year marriage and live to be 91. It's a happy ending that satisfies me.
