Castle reluctantly accepts the case of former study friend Eva Whitfield who suspects her wealthy husband, Cole, of adultery. When he comes to deliver proof at night, he witnesses her bloody body being dragged away and put in a car. Castle follows, trying to find where the body is being dumped but is knocked unconscious. When he wakes up, he contacts the police but they can find no corpse or any evidence or sign of struggle at the house, yet she's missing. Castle risks stalking charges by following Cole. But, when both Eva and the Cole show up dead, Castle comes up with an alternative theory. Meanwhile Ryan's devious attempt to get Esposito a fitting date before the ski trip by dating site behind his back doubly backfires.
