Hi everyone, so the movie I can't remember seems impossible to find because I don't know much but here I go:
As far as I remember the movie was released in the 21st century, basically it was about an undercover cop (i think a blonde woman) who meets up in a hotel with a crew of picked out people by an unknown boss, basically they are planning a heist and working for someone they dont know, like a myth. Let's just spoil it right away whatever, one of the crew members, a black guy who does the tech/computer hacking stuff for the team turns out to be the boss and at the end takes off with the score/money, so a plot twist. About the heist itself i dont remember a lot, i know there was confusion on the police's part since they were tracing the undercover cop but they lost contact and I think they might robbed a different place as well so they couldnt find her, lots of panic.
I hope that's enough, thanks in advance!
