Description:

The smallest of small-time criminals, Ernest Stickley Jr. figures his luck's about to change when Detroit used car salesman Frank Ryan catches him trying to boost a ride from Ryan's lot. Frank's got some surefire schemes for getting rich quick – all of them involving guns – and all Stickley has to do is follow "Ryan's Rules" to share the wealth. But sometimes rules need to be bent, maybe even broken, if one is to succeed in the world of crime, especially if the "brains" of the operation knows less than nothing.
