There is a man on a ledge. The man in question being Nick Cassidy, a former cop. He is serving 25 years.We’re taken one month earlier in time to Sing Song Correctional Facility, where Mike Ackermann is visiting Nick. Both were partners before Nick got arrested. Mike tells him that his father is dying. Nick is allowed to attend his father’s funeral later. And it is there that he makes his escape, after picking up a fight with his brother, Joey Cassidy.
Present day, we see Nick Cassidy checking into a room at Roosevelt Hotel and having a meal. He then proceeds to wipe his fingerprints off of everything and climbs onto the ledge at the 21st floor. He goes by the name of Walker now. Enter Detectives Dante Marcus and Jack Dougherty who have been assigned the case. Nick asks for a Detective Lydia Mercer and she is called up to handle the negotiation. In the hotel room, Nick leaves behind a statement, ‘I will exit this world as I entered-Innocent’.
