**SPOILERS*** Jack Klugman in a rare dramatic as well as tragic role is the klutzy just divorced jewelry salesman Arthur Crews who's looking for love and a night on the town only to find what turned out to be his worst nightmare instead! Having met pretty but a bit strange Vivian North, Diana Hyland, at a party Arthur made a date with her the next Saturday night planning to get to know her better or even start up some kind of romantic relationship with the young lady. Both Arthur and Vivian have been recently divorced and this seems like the right time for the two to get back to the dating scene.
It's not that long that Arthur begins to see that there's something loose upstairs in Vivian's head and has second thoughts in meeting her. This all starts when Vivian's car was stolen from her and the police were called in to find it. What they found out is that Vivian got gloriously drunk the night before and gave her car for a spin to this local neighborhood Romeo Richard "Big Dick" Wilkes, Alex Cord. As it turned out "Big Dick" has a long criminal record in abusing and taking advantage of lonely woman among his other crimes! Getting in touch with Vivian's ex movie projectionist Phil North, James Patterson, the cops soon realize that they have a first class nut case on their hand in finding out from him that his former wife Vivian is not only crazy and delusional, she claims to have lots of imaginary or invisible friends, but has both suicidal and possibly homicidal tendencies as well.
****SPOILERS***** Back at Arthur's pad where he took Vivian to spend a quite evening with she goes completely bananas when he realizing how off the wall the lady is finally gets up enough nerve to tell her that she just isn't his type. In a sudden show of white hot fury after being rejected by Arthur, who by now knows that the two weren't quite meant for each other, Vivian grabs his licensed gun that he has as part of his job as a jewelry salesman and blast the poor guy away! In the end Vivian coming to the local police station where her ex-husband Phil is present she has a complete breakdown and is finally taken away after the police relieved her of the late Arthur's gun, that she threatened to shoot herself with, to the hospital psychiatric ward's isolation chamber for an around the clock suicide watch as well as mental observation.
P.S Arthur Crews was a tragic figure in all this but it's Vivian's ex-hubby Phil whom you feel even more sorry for. He not only had to suffer living with her all those years until he finally called it splits-ville but now has to live with the fact he was married to a potentially crazed and man hungry murderess without even knowing it!
