Killing Mary Sue

Mary Sue Harper, the problematic step-daughter, is introduced as causing chaos in the life of Senator Bradley Weiner, who is engaged in a fierce re-election campaign. Bradley is depicted as strategizing to eliminate her to improve his political prospects amidst scandals. Mary Sue remains unaware of her stepfather's treachery and seeks his affection.

The first hired assassin arrives at the Weiner household with the intent to kill Mary Sue. However, she remains unfazed and mistook the assassin for a prostitute, inadvertently killing him herself while demonstrating her rough foreplay. This initial attempt fails entirely.

After the failure of the first attempt, Bradley relies on Knox to hire more lethal assassins. Knox sends in a military death squad to eliminate Mary Sue, but she surprisingly kills all of them in a shootout, relying on her video game skills.

The last effort involves Knox arriving personally to kill Mary Sue. However, she quickly subdues him and humiliates him in the process. Knox's failure prompts Bradley to intervene.

To prevent Knox from revealing their conspiracy, Bradley kills him during interrogation and blames his scheme on his political rival, Anita Koch. This escalates tensions and prompts Mary Sue to threaten and suspect Anita.

Bradley uncovers that the housekeeper, Carrie, is a KGB spy planted to gather intelligence. She then promises to kill Mary Sue in exchange for Bradley’s loyalty, marking the infiltration's rise.

Carrie, now under the alias Svetlana, lures Mary Sue to a remote woodland location. She tries to induce her with toxic drugs, but the plan fails. A fierce shootout ensues, ending with Mary Sue prevailing with ease.

Vladyslav Volkov, an overseas employer, reveals that Mary Sue has been brainwashed as a sleeper agent. However, she resists and kills Volkov, regaining control of her actions.

Recognizing Bradley’s manipulations, Mary Sue and Janine turn against him, ending their toxic relationship. Bradley's subsequent fate is implied to be suicide, leaving his political career in jeopardy.

Mary Sue and Janine depart, while Bradley’s death is reported as a suicide. Anita Koch becomes the leading candidate for the Senate, but her own household harbors secrets that suggest chaos will persist regardless of election results.
