Leyla and Lucien's field trip to the National Gallery of Art reveals more than the teens are expecting. After noticing something odd in a special exhibit painting, they try to convince the director of the Gallery that there's something wrong with the artwork. When they're not believed, the teens are determined to prove they are right. As they probe further, the teens uncover evidence of murder, deception, and black market dealings that may cost them their lives. Will the two friends be able to gather enough evidence to support their theory in time? Or will Leyla and Lucien go missing, leaving the Gallery to purchase clever forgeries?
