It starts with Kelly Sherwood (Remick) driving her thunderbird (or is it a cadillac?) though dark San Francisco - then she arrives home and is terrorised in her garage by the Mystery Man .... Kelly is a bank cashier and he wants her to steal $100,000 from the bank for him, or else she and her kid sister (Stephanie Powers) gets it, and she must not contact the police. He ups his game of terror but Kelly contacts the FBI - enter Glenn Ford as agent Ripley.
There is no romance here - he is the guy on the case and she is the terrified victim. The plot twists and turns for all of its 1.58 running time to the exciting climax at a basebal game when the killer (who has managed to kidnap the sister) is finally cornered ..... Remick of course is marvellous and Glenn is his usual solid self. I liked it a lot. Lee said in her 1988 "Films In Review" interview, where she looked back at her career: "That movie still looks good. It's well made, tightly knit."
Lee, Blake and Mancini teamed again that year for the even better DAYS OF WINE AND ROSES - more on that at Lee labels
