 Handyman Harve Case robs local businessman Fred Briscoe of $11,000 in donations to the "Mother s March" for the children s wing of the local hospital. The initial investigation points to beautician Mabel Wayne, a committee member who knew how the funds would be transported. When Dan Mathews travels to Mabel s Hill-Top Beauty Salon to question her, he finds that she had been assaulted by Case after she found him trying to plant some of the stolen money in her salon. Dan learns that Case had previously overheard Mabel and Lucy Briscoe talking about plans for transporting the money. Case fires at Dan and attempts to escape on a motorcycle, but he is soon hemmed in by strategically placed roadblocks.
