Mean Guns (1997) on Netflix

Plot summary

A crime syndicate has access to a prison that has not yet opened. The day before it does, Vincent Moon assembles a hundred killers who have wronged the organization and hands out guns, ammunition and baseball bats. They have six hours to fight one another, and $10 million is hidden in the building for the last three survivors. Cam, an accountant, is intercepted while carrying pictures that document the syndicate's illegal activity, which she means to hand to the authorities, and she cannot bring herself to shoot anyone. She joins Marcus and D, two professionals, and then Lou, who holds Marcus at gunpoint for a moment before the others take him in. Lou leaves a small girl named Lucy in his car outside.
