The Rockfords work with Sgt. Becker to solve Rocky's friend's murder. When 6 tractor trailers from the same depot are hijacked by a gang, there must be a connection with the killing, but who desperately needs tons of ladies' underwear, grapefruit and dynamite ? The proud Rocky resents Jim taking care of him, making the slew of hit-men even harder to combat for Dennis and a very confused LAPD.
