Stormy Weather

During a heavy storm, Jack Lord, and Belle, are asked to safe-guard a diamond exhibition. Belle pretend to fall in the rain to be able to check inside a truck. She sees four boxes, filled with something. In the rain she follows this truck, and in the rain, and wind, she helps the driver with the boxes. Belle takes the boxes to the police station, where after opening one, they find all the diamonds that should have been at the exhibition.
