Even a robot dog can sniff out trouble... USAF Lieutenant Samantha Spade is in the heat of the west Texas desert testing a dog-like robot for military use, when the device leads her and her team to a pick-up truck. The driver comes at them with a gun-and is shot in self-defense by Sam's friend. And then a gruesome discovery is made: three human heads in a cooler in the back of the truck. Because the dead man was on the FBI's most wanted list, Sam stands to get a hefty reward. Too bad the technology to keep her shady ex-husband from sniffing out cash has yet to be invented. His appearance, along with frightening issues from her boyfriend's past, make it hard to tell just who is responsible for the pipe-wielding thug who attacks her. All Sam knows is that her luck has taken a doggone turn for the worse...
