Because one of them is in great trouble.. in a moment important for her career- the other one switches places with her.

- a corrupt female prosecutor whom seems to have the hots for the good guy, while being probably liked by/and working for the bad guys..;
- corruption and stupidly within the police force and prosecution;
- a harismatic male psychopath as the main villain.
