***SPOILERS*** Always wanting to be his own man industrial chemical researcher Tom Benning, Tom Tryon, feels trapped in his job at Continental owned by his father-in-law R.Randolph Weirtherill, David Lewis. With his Elizabeth Taylor look-alike, but much prettier, wife Jan, Myrna Fahey, wanting him to get ahead in the business all Tom can see is that he'll be stuck at his job as a chemical researcher with the boss, old man Wertherill, having no confidence in his work at the plant. That's until sleazy Alan Parson,Liam Sullivan,comes on the scene and get's him to steal and sell all the secrets of Continental to a likewise chemical plant overseas. And for a cheap $10,000.00 payoff in return no less.
At first rejecting Parsons offer Tom later gives in and takes the pay-off money only to change his mind later after a heart to heart talk with Jan. Now facing not only the loss of his job but being indited for industrial espionage Tom is screwed either way he turns. By going to Mr.Wertherill and the police to report Parson or going along with him by getting deeper into the trouble then he's already in.
***SPOILERS*** It takes a lot of soul searching on Tom's part but in the end he does the right thing. That's by stringing Person and his thugs along and then lowering the boom on them when he gets enough evidence, the secret papers that he stole for them, to hang them with. Still Tom has his work cut out for him in trying to save Jan's life who was kidnapped and held as ransom by Person & co. Which set up the films exciting car chase climax that had Person & Co. end up getting caught by the highway patrol in their attempt to keep Tom from talking. As for his job Tom really doesn't need it now that he sees that he can make it on his own without the help of his father-in-law Mr. Wertherill with his daughter Jan finally sticking by her husband's-Tom Banning's-side.
P.S Sad to say the strikingly beautiful Myrna Fahey wouldn't live to go on to bigger and better roles on TV and in films dying of cancer in May 1973 at the age of 40.
