The BAU heads to Detroit, Michigan where community activist Russell Pearson is found murdered. His latest cause was opposition to a proposed gentrification project of high end condos, however it was recently discovered that he took bribes from the condo developers. As identified by the tag next to Pearson's body, the murderer is renowned street artist, Morpheus, whose actual identity is unknown. Morpheus, whose art has a social activism bent, would have been on the same side as Pearson of the condo development issue up until the discovery of the bribes. Morpheus, who works primarily in New York, Los Angeles and the Gulf coast, generally shows up after an issue has become known, leading his voice to the cause through the art. Morpheus' art first appeared in Detroit a few weeks ago, next to a burnt out car where a homeless mother and her infant died, the car where they were sleeping. By the time the team arrives in Detroit, Morpheus has struck again, this time kidnapping Corinne Wallace, the infant daughter of one of the condo developers, Stuart and Katherine Wallace. This abduction, with no ransom note, changes the focus of the investigation, where Morpheus' end game is a personal one, and with he not caring about showing himself after all is said and done. The team believes the focus of the crimes is the baby itself and not the condo development per se. They have to find any connection Morpheus may have to anyone else - he who could not have stayed underground for close to a decade without help - and if they can if there is a connection to a baby. The task of finding Morpheus may also be difficult as Detroit is not his general base of operation. The other possibility is that the art is a forgery and that someone has a personal vendetta against Morpheus. Meanwhile, her work take takes its toll on Lewis' home life.
