He was known to have told his sister he made a big deal before he died and deposited $10,000 in the Calico bank. He died leaving a young son Jason and sister Ellen who both believe Sam was innocent. After Sam's funeral Jason finds a Wells Fargo strong box in the attic while picking up his dad's things.

Hardie agrees to pick up the box and investigate but that any new findings must be based on hard evidence and so far it looks bad for Sam. When Jason learns of Hardie's arrival, he hides the box and refuses to return it until he fills it with the $10,000.
