The matter of catching Clyde the mouse turns into an obsession with Doctor Roller.
Lum gets onto Abner for his interference that caused the explosion of pest control chemicals. They discuss the aftermath of the explosion. Still, Doctor Roller the pest controller isn’t discouraged.
The exterminator turns to more destructive measures in his quest to concquer that one single mouse. Lum has had enough, and would rather have the mouse than the demolition job Doctor Roller is carrying out on the store.
It’s going to cost Lum and Abner more to get rid of their exterminator, and do repairs than any damage that the mouse could do in a life time. The determined pest controller refuses to stop until he catches that mouse. His reputation is at stake.
PS: Howard McNear is the guest voice to portray the obsessive Doctor Roller.
