New York City, 1976. Meet Regan and William Hamilton-Sweeney, estranged heirs to one of the city’s great fortunes; Keith and Mercer, the men who, for better or worse, love them; Charlie and Samantha, two suburban teenagers seduced by downtown’s punk scene; an obsessive magazine reporter and his idealistic neighbor --- and the detective trying to figure out what any of them have to do with a shooting in Central Park on New Year’s Eve. When the blackout of July 13, 1977, plunges this world into darkness, each of these lives will be changed forever.
