Ask AI: write me a plot bout a killing game in a prison with 16 characters

In a high security prison, sixteen inmates find themselves selected to participate in a twisted game. Each of the inmates has a dark past and a specific skill set, and the mysterious benefactor behind the game has promised them their freedom if they manage to be the last one standing. As the killing game begins, the sixteen inmates are given specific instructions and clues about how to outwit and eliminate their opponents. Some of them try to form alliances or find ways to cheat the game, but trust is scarce and alliances are quickly broken. As the game progresses, the stakes get higher and deadlier. Several of the inmates are found dead under mysterious circumstances, leading each of them to become more paranoid and defensive. Old rivalries surface and alliances crumble, leaving the inmates even more vulnerable. But as the game reaches its climax, a shocking twist is revealed: the benefactor behind the game was one of the inmates all along, and they wanted revenge on the others for their involvement in the crimes that led them to prison in the first place. With the truth finally revealed, the game becomes a battle for survival as the remaining inmates must face off against the vengeful mastermind behind the game, all while trying to stay alive and win their freedom. In the end, there can be only one survivor--but at what cost?
