Shadows of Tomorrow

A family consisting of parents, their two adult children, and their cat Berta suddenly finds themselves in a situation where they don't know what's happening.
Out of nowhere, a warning about an unknown danger appeared on TV, and since then, the television and radio have gone completely silent. There's no signal, and even the emergency hotline is unreachable.
The vast majority of people from the village have left to join relatives in the cities to be together and find out what's going on. The village is now empty. The fear of the unknown is overwhelming. You know something is happening, but you don't know what.
Riots? An unknown disease? An alien invasion? None of these can be ruled out. Overnight, the family is left without any information about what's going on.
What's happening to their relatives? What's happening to the world? When will this end? Will this end? These are questions to which they have no answers.
The only thing keeping them sane is being together and the hope that the world will one day be all right again.
