'Brent works as a trolley boy at the local supermarket. Nathan, his friend, drives the trolley tractor until a world-record trolley-push attempt in the car-park ends with him getting sacked. Nathan's replacement, Darren, is up to something dodgy, Brent is sure of it, and when a priceless diamond necklace goes missing Brent is convinced that Darren is involved . . . but how can he and Nathan prove it and solve the crime.'
