Rita Hudson accepts delivery of $35,000 worth of imported diamonds on behalf of her employer, Mr. Van Dyce. She is immediately abducted by thieves Ernest Zober and Chuck Barton, who received information concerning her movements from Lydia Stevens (Mr. Van Dyce's executive assistant). Dan Mathews and Sergeant Williams investigate and deduce that Rita was a victim rather than a perpetrator. They suspect that Lydia may be involved and Dan drops hints that that the Highway Patrol has a detailed description of Zober and Barton and their car. When Lydia panics, Zober and Barton decide to abandon her and go meet "Mr. Darrell", the prospective buyer of the gems. When Lydia realizes she has been duped and abandoned, she tells Dan all she knows. The information enables Dan and his officers to trap "Mr. Darrell" at a roadblock. They quickly locate Zober and Barton as well, and an armed confrontation ensues with Rita perilously near the line of fire.

Dan Mathews and Sergeant Williams come to the same conclusion and stake out Gloria Jordan's farm. Gloria attempts to flee to Chicago after mailing the money to her destination, but Joe intercepts her. She is treated roughly until Dan Mathews and Sergeant Williams utilize the element of surprise to capture the three and confirm that the package they recovered from Gloria's mailbox contains the stolen money.

Pyromaniac Judd Patterson sets a warehouse ablaze and gets away in a stolen car. He abandons the car and hitches a ride with farmer Claude Norpel, who offers him temporary employment as a hired hand. An arson investigator gives Patterson's name as a possible suspect, and Dan Mathews and Sergeant Williams trace him to Norpel's farm. However, they arrive after he has already assaulted Norpel, knocked him unconscious, and is about to set the barn ablaze with Norpel still in it. Sergeant Williams distracts Patterson while Dan Mathews overpowers him, but the barn is set afire in the scuffle. The two Highway Patrol officers have only seconds to rescue Norpel and extinguish the blaze.
