Nine people, mostly strangers to each other, are linked together when they are held hostage in a bank robbery gone wrong. In each episode, viewers learn new details of the 52 hour standoff, of which only brief snippets are seen.
The Pilot episode establishes the events which the rest of the series will embellish. Two men enter the bank, armed, and quickly restrain both the security guard and an off duty police officer. Viewers see details of what brought each person to the bank that day.
Some time after the end of the standoff, the former hostages arrange a meeting with one another in an effort to stay in touch and help each other. Various characters also form relationships apart from the group and maintain regular contact with each other during the week, while others are connected through relationships that predate the events in the bank.
