Working the burglary detail, Joe and Frank visit the crime lab. Frank shares a word on some domestic troubles, playing cards with his wife and friends. Reviewing the data from the crime scene, some common threads begin to develop about the break ins. The tools used might form an important clue in stopping the crimes. A tip comes in from an unusual source, and the cops set out to track down a known thief. Is he their man, or just part of a ring of burglars.
When word comes that a big job is planned, Joe Friday arranges to catch his bad guys red handed.
