Rule No 1: Don't make a sound. Rule No 2: Never leave the path. Rule No 3: Red means run.

A family is forced to live in silence while hiding from creatures that hunt by sound. Parents do whatever it takes to keep their children and soon to be new-born safe in a world full of creatures hunting every sound they can hear. Not a sound can be heard from the family hiding in silence, but all it takes is one noise and everything can go wrong.
