Guess who's gonna die

That one person could be you or a family member. Choose wisely.

I wonder would they realize they are part of that seven billion.

There's actually a really nice short story with the same plot as this

I remember that movie and I don't think she died from her own button but she died exactly when another family pushed the button.She died by her husband killing her to save their son from losing 2 sences.When they pushed the button the same thing happened to another family.The moment she pressed the button the family which previously had the box went to shit and the husband killed his wife the moment this gir presses the button.And the cycle continues but in order to win you just need to not press the button.

You die

What is that movie called?
