After decades of neglect, Castle Heights Hospital, a symbol of the city's segregated past, has been packed with dynamite and is ready to be demolished. No one knows that a gang leader, now in prison, hid the 3 million dollars in cash he stole from his rivals inside the abandoned building. Now, three desperate parties want the money – a blue-collared ex-fighter (Scott Adkins) who finds it while working as part of the demolition crew, a prison guard (Dolph Lundgren) willing to do anything to pay for his daughter's cancer treatment, and a ruthless gang who claim to be the rightful owners. The demolition charges are set, everyone clears out and the Castle is set to fall in 90 minutes.

The clock is ticking. Who will seize the cash ... and will they get out alive?
