Mean Guns

Vincent Moon unveils the prison and gathers 100 killers. He arms them with weapons and gives them six hours to fight to the death. A $10 million prize is hidden in the prison and will be split among the last three survivors, but Moon’s plan is to sweep in and kill everyone when time runs out.

Cam teams up with Marcus and D, establishing a tentative plan to navigate the deadly competition. The group is joined by Lou after he briefly detains Marcus at gunpoint and is reluctantly accepted. They intend to survive and claim the prize.

Lou discloses he is caring for Lucy, a girl left in a car outside the prison. He joins the alliance to secure a future for her. This revelation adds a personal motive to the brutal game.

The four broadcast an announcement over the prison's PA system, claiming they have found the money and challenging others to fight for it. Chaos erupts as the participants clash and many are killed in the melee. Cam slips away to avoid participation.

D abandons the group but is killed by Lou when their fragile alliance fractures. The turn of events shows Lou's willingness to remove threats by lethal means. The immediate danger within the prison escalates.

Moon reveals the actual location of the prize within the prison. Marcus finds two briefcases at the spot and takes them, while a third is left behind, rigged with a bomb. The strategic distribution of loot sets up the final confrontations.

Marcus brings Lucy into the prison to assist in stealing the cash. Barbie discovers the bomb and is killed when it detonates, blowing off the top of her head. The danger of the prize escalates to include innocent bystanders.

Cam retrieves the photographs she planned to give to authorities and shows them to Marcus. She realizes the scope of the syndicate's money laundering and the depth of their corruption. This new information strengthens her resolve to expose them.

Marcus reveals Moon's motive: he brought Marcus into the game hoping Marcus would be the last person standing. This confession reframes the deadly contest as a calculated trap rather than a random brawl. The plan hinges on forcing a final showdown.

Moon summons Cam, Lou, Marcus, and himself to a climactic four-way confrontation. Each is given a gun, and Moon keeps one for himself but does not load Lou's gun. The stage is set for a controlled, fatal duel.

In the tense standoff, Marcus shoots Cam and then Lou, trimming the field. Moon then attempts a quick-draw against Marcus and is killed by Marcus. The delicate balance between the players collapses under the weight of greed and paranoia.

The wounded Lou claims Lucy is his biological daughter, adding an emotional twist to the deaths. Marcus and Lou kill each other, leaving Cam gravely injured but alive. Lucy's fate remains central to the survivors' next moves.

Cam awakens to Lucy standing over her; Marcus had killed Lou at Lucy's request and only grazed Cam, allowing her to fake death. Cam escapes in Lou's car with Lucy and the prize money, preserving both the girl and the winnings.
