Sam (Chris Hemsworth) and Leslie (Victoria Profeta), their finances in ruins, think their luck has changed when they find a briefcase full of money. Rather than turn the windfall over to the authorities, they decide to keep it in the hope of buying themselves a better life. But no sooner have they spent the cash when a sinister stranger (Sean Bean) appears on their doorstep, and he refuses to let the couple off the hook until they pay back every penny.
