Diamond Heist

It's 2003 in London England  You are part of an elite team of secret service agents getting ready to raid The Mobsters hideout here in London . The Mobsters have stolen the world's largest diamond " The Cullinan Diamond". Your mission (if you dare to take it) is to find their hideout and break into their secret vault and recover the diamond while they are attending a red-carpet event tonight. Time is crucial and you only have 60 minutes before they return. This is your team's only chance to complete the mission before the Diamond is sold to the highest bidder tomorrow night on the black market.
