lady kingpin

I want to make a movie where a criminal mastermind called “The Boss” is controlling  the city’s underground trade, but when they finally raid this mysterious kingpin’s building they find his office empty except for the small Filipina cleaning lady who is confused and scared, so they evacuate the workers and arrest who they can

Not knowing that that unassuming cleaning lady was actually “The Boss” in disguise and she walks right out of the building without once being seen as a threat
