When seventy-nine-year-old Anton Watson enters Serenity Haven, an Alzheimer's facility in Tomball, Texas, he seems like an ordinary, frail, old man. No one would guess that Anton has lived a double life since he was a boy of thirteen growing up on a small farm in the south Texas valley. In a short period of time when he is a teen, Anton loses his mother, his father, and the family's farm. It's on this farm that evil takes hold of the young boy.
Anton's rage is at first directed toward the farm's animals; he knows that acting on his other fantasies and thoughts will lead him straight to prison and even death row. But one stormy night, he can't control his urges, and a serial murderer is born. Neither his wife, Doris, nor his son, Victor, knew they were living with a killer.
His motto-be patient, be wise, and be fast-served him well, and he has gone unnoticed by the police for over fifty years. Old age and a frail body put a stop to his malevolent behavior more than a decade ago. Now living in an Alzheimer's facility, his horrible deeds come to the forefront as he loses his short-term memory and dives deeper and deeper into his horror-filled past.
