Tommy takes Genevieve on a tour of Ground Zero and tells her why the 9/11 footage of Jimmy Keefe was so haunting. And Franco's 9/11 conspiracy theories come under attack. Literally. Meanwhile, Mike's bar proves to be a success; Sean learns that he'll have to quickly come up with $12,000; Tommy and Lou have a falling out; and Janet tells Tommy why she sent Katy to an upstate boarding school.

Tommy is haunted by ghosts of 9/11---and other ghosts, including his dad, his brother Johnny and his cousin Jimmy. Meanwhile, Sean's health continues to deteriorate and black Shawn is still missing; Needles and Lou try to talk Franco into entering a FDNY boxing tournament; Mike befriends Damien; and a nervous young man enters the bar just after closing time.
