In the wee hours of the morning, four men in latex masks enter the elegant Montclair hotel in midtown Manhattan. After detaining the night staff, Frank Belmonte, one of the best jewel thieves in the business, breaks into the safe-deposit boxes held by the rich old residents of the hotel. "Frankie Rocks" takes roughly ten million dollars' worth of jewels from the boxes.

The heist seems to be running smoothly until some unexpected guests arrive at the hotel and the burglars are forced to take them as last-minute hostages. But these are no ordinary hotel guests, and three of the four thieves aren't really looking for jewels. Their agenda is one of national security.
