I'll type out the plot I had in mind. The boss can be either gender, it doesn't matter.

There is a smattering of gangs in a single city, but the group with the most power is a Mafia-like group. One of the other groups starts to advance, gaining power and ground in the city. The head of the Mafia wants to cut it off at the head, so [s]he has the daughter of that gang's leader kidnapped and held for ransom. The daughter is against the gang life, but she is continuously dragged into it and she is fed up with both sides.
