When Vincent van Gogh's long-lost 'Portrait of Monsieur Trabuc' turns up unexpectedly at the Metropolitan Museum of Art - a $50 million painting shipped from Argentina via UPS, like an ordinary package - the case goes to NYPD Major Case Squad detective Clay Ryder. Ryder discovers that in 1944, the painting was reported as a Holocaust art theft in Paris. The accused thief, a notorious German SS officer, died in a car crash, leaving the Van Gogh's whereabouts a mystery. After Ryder tracks down the painting's rightful heir, Rachel Meredith, the Met presents the portrait to her in a spectacularly publicized ceremony, and the case is considered closed. But isn't. Israel's Mossad soon pays Ryder a clandestine visit, seeking the SS officer, who they believe may still be alive. Meanwhile, art dealers, auction houses, and museums vie to buy the Van Gogh. When Rachel refuses to sell her legacy, the situation goes from predatory to violent. Ryder has to race against time to outmaneuver a cunning mastermind who will commit as many murders as it takes to get hold of the Van Gogh.
