 Dean and Sam read on the newspaper about a young couple slashed in New York and they decide to investigate. They disclose that the victims have just bought an antique painting of 1910 in a beneficent auction and when they check its provenance, they find that three other families that owned the painting had been killed in the past. Further, the head of the family had murdered his wife, sons and stepdaughter with a razor blade. When the painting is sold to a local and she is also murdered, Sam and Dean with the support of the daughter of the auctioneer, Sarah Blake, disclose the truth about the killer.
