Snowmageddon

When the Miller family discovers a mysterious gift outside their home on Christmas eve, they could never imagine it would contain the power to doom their idyllic mountain community. The gift contains a snow globe with a perfect reflection of their own town inside. When they shake it, snow even begins to fall - whatever happens inside the snow globe, happens to their town for real. But when buttons
on the snow globe unleash a series of terrible disasters on the town, the family must band together and find a way to destroy it - before it’s too late. (official distributor synopsis)
