Rosa, a young alcoholic who has bottomed out and is reduced to working as an office cleaning lady, gets lucky and finds a lot of money.
Well, not that lucky, actually; the money is next to a dead guy, and people want the money back. Bad people.
Rosa is a nice girl, but it turns out that if you get her mad — well, okay, really mad — she’s not that nice, really. Er, come to think of it, she’s not nice at all. I mean, she has a good heart and all that stuff, but she also has an unexpected instinct for how to use weapons.
Which, if you provoke her, could prove to be a serious problem. The fact that her boyfriend is a cop isn’t helping; and before you know it, the cleaning lady has turned into someone who is making things very messy indeed, for a whole lot of people.
