Detective Finger, I Presume?

The club that B.J.'s trucking company owns is robbed and the thieves make away with jewels and a very valuable painting. When a valuable painting is stolen from BJ's office, an inept police detective, Fred Finger, proves to be of no help, so the trucker must crack a burglary ring of female bodybuilders and nail a crooked cop. Defective Finger believes that BJ had the painting stolen to collect the insurance money, so BJ sends Stacks and Cindy to infiltrale a ring of female bodybuilders and gymnasts he suspects are the thieves. Meanwhile, a crooked Grant underling, Capt. Dryer, makes plans to eliminate Stacks and Cindy after one more theft.
