The story takes place in the bustling metropolis of New York, where a banquet is being held in a museum. What the people attending the banquet did not expect was that four uninvited guests rode into the hall on tall horses and stole an exhibit from the museum. Afterwards, four bodies were found by the citizens, but the exhibits they stole were missing. Tess (Mira Sorvino), who experienced the chaos at the scene, was sensitive to the abnormality of the matter. She teamed up with the FBI detective Daly (Scott Foley) to thoroughly investigate the whole incident and unearthed the unknown dark secrets hidden in the Knights of the Crusades. At the same time, a knight named Martin (Stéphane Demers) gradually surfaced. He was the last surviving Templar Knight. In him, there may be the key to solving the mystery.
