"There are unknown volatile substances that journey through the tunnels of the New York subway, the result of 120 years of urban activity."
A former criminal detective. A couple who loses sight of each other in the subway. A multinational corporation with dubious methods. A macabre journey into the past...
An advertisement published in a New York newspaper catches the attention of Steve Morgan, a former criminal investigator. Duvall, one of the leading multinational companies in the sneaker market, presents its latest model. Steve notices in the advertisement insert that Duvall has integrated an open proposal addressed to the newspaper's readers. This, undetectable at first glance, did not escape Steve's notice.
Matt and Kate Walsh, who have just arrived from Ireland, settle into the hotel they have reserved not far from Grand Central Terminal. After spending the night, they begin their first day of city exploration and decide to head to the southern part of Manhattan. As they approach the station that will take them to the Statue of Liberty, they lose sight of each other.
Steve and Matt do not know each other. They are far from imagining that an event will take them back years into the past, on the trail of their childhood where they will make a gruesome discovery.
