On her way, she meets Roy, a mild-mannered video store owner who is discontent with his unexciting life. Harley figures Roy would be the perfect addition to her plan and reels him into her scheme. Soon, the two are running from the mob and heading for the border. In a surprising twist, Roy and Harley discover that sometimes the one you trust the most is the one you should trust the least.
