Badass Inc.

You are a (really badass) contract killer on her latest mission. You usually prefers a very direct approach. “Head-on, gun loaded, never give the target the time to realize what the hell is happening”, is her motto. But this time, her clients want her to kill the contract in a non-conventional way. Something original. So she decides to lock the victim up inside his own apartment and leave him to die from starvation.
