Killing Mary Sue Movie Cast, Plot and Everything to Know

Plot

Bradley Weiner is one of the most powerful senators in Washington. The only problem? His oblivious step-daughter, Mary Sue, refuses to stay out of the news with her partying, hookups, and drugs. As the bad press risks the Senator’s chances at re-election, he determines that his only choice is to have Mary Sue murdered. It’s perfect! Killing two birds with one stone – eliminating her from his career, and creating true sympathy for his tragic loss. However, after Mary Sue unintentionally dodges the killer and (through a bizarre course of events) in fact kills him herself, a monster is unleashed inside of her that clearly stems from someplace deep and scary. It’s going to take a lot more assassins and a lot more effort to put away this firecracker.
