Police Sergeant Mike Dunwoody is a small-town cop, nearing the end of his service in New Mexico. Having moved out of the big city some years ago to give his kids a chance; he’s now looking forward to a long retirement now they’ve grown up and following their own careers.One evening, whilst waiting for two local miscreants who use the highway as a drag strip for their pickups, he sees something odd in the desert and goes to investigate.A flash flood fills the dry gulch with swirling water, and he sees what he believes is a child, being swept off to certain death by the turbulent water.Entering the water with a rope tied off to his patrol vehicle, he risks his life to save the child, but as he reaches dry land, he discovers that it is not a child, at least not a human child.Years of the wrong food, bad sleep patterns and a general lack of care for his body, his heart suffers a potentially fatal attack, so his sacrifice leaves the captain of the alien ship with something of a quandary.Mike’s body is beyond repair, but as the individual he saved is special, the captain decides to revive Mike, but so as not to risk certain exposure; the cloned body is slightly modified so the new Mike will not be able to tell of the experience.The modifications?Mike wakes up as Michelle; and Michelle is an awful lot more efficient than most girls are; once she gets used to the being a girl bit, that is.
