Stan is called out to Possum Kingdom Lake in Central Texas where a boy scout has been killed in a tragic Jeep accident. At first glance it appears to be just a typical case of reckless teenage driving, but when the teenager, Steven Caldwell, is charged with negligent homicide he insists the accident wasn't his fault. He claims he was distracted by an alien spacecraft that suddenly appeared overhead. Stan is reluctant to take the case since, in order to get Steven off, he'll have to prove aliens have visited Possum Kingdom Lake!
