As the three strangers, a young woman, an older man, and a middle-aged woman, struggle to come to terms with their situation, tensions run high. Each of them has their own secrets and reasons for being in the mansion, and as they try to work together to find a way out, it becomes clear that there is no easy solution.
As the days pass and supplies dwindle, the group becomes more desperate. The young woman, who has a medical background, suggests that they draw straws to decide who will be the one to sacrifice themselves for the others. The older man is hesitant, but ultimately agrees to the plan.
However, as they prepare to draw straws, it becomes apparent that the middle-aged woman has other plans. She reveals that she has been manipulating the situation from the beginning, and that she believes the only way to truly escape the mansion is for her to be the one to kill the other two.
A tense and deadly game of cat and mouse ensues, as the three strangers fight for their lives and struggle to outsmart each other in a desperate bid for freedom. In the end, only one will survive, but the true cost of their escape will weigh heavily on their conscience.
