A quiet, middle-aged couple living in Chelsea start to receive threatening letters through the post - and then things take a sinister turn as their beloved poodle, Tina, is kidnapped. Should they comply and pay up the ransom?
Despite complying with the kidnapper's demands, Tina isn't safely returned to her owners as agreed. A smart young copper from the local force (who took the couple's problem seriously) decides to investigate - despite the indifference and cynicism of his police colleagues.
Thanks to Clarence's intervention, the dog kidnapper is apprehended and charged. But the CID officers' cynicism towards the case continues, leaving Clarence in a position of distrust, and the dog's owners vulnerable.

But, as police investigation into Kowajinski's death increases, Clarence is left to his fate.
The police investigation into Kowajinski's death continues, with Clarence still their number one suspect. After a night of intense interrogation, they finally let him go - but is it really the end?
