The familiar becomes sinister when Tom Krupp returns home at 6:30 PM to find his front door ajar. Inside, life appears suspended in mid-action: a half-sliced tomato on the cutting board, water boiling on the stove, Karen's cooking playlist still playing. Her purse sits on the counter with her phone inside, but her car is mysteriously absent. As minutes stretch into hours without explanation, Tom's concern morphs into full-blown panic. Across town, Officer Sarah Kirton responds to reports of a vehicle driving erratically through an industrial district. The silver Lexus blows through four red lights before crashing at nearly ninety miles per hour. The registration: Karen Krupp of 47 Dogwood Drive. At Mercy Hospital, Tom identifies Karen's blood-spattered white cashmere sweater and the sapphire pendant he gave her for their anniversary. When she regains consciousness thirty-six hours later, her whispered response sends chills down his spine: "I don't remember anything... Why was I out there?" The situation darkens when three teenagers discover a corpse in an abandoned restaurant just blocks from Karen's crash site-a middle-aged man executed with surgical precision. As Detective Marcus Rasbach begins connecting these seemingly unrelated events, Tom's perception of his perfect marriage starts to crumble. Was his wife ever who he thought she was?
