It is the astounding true story of twin sisters who only communicated with one an other. As a result, they created a rich, fascinating world to escape the reality of their own lives. The girls were unpredictable since childhood. They would attend class by walking in synchronization, mirroring each other’s steps, coming to a silent stop with no explanation.They could crumple to the floor if someone addressed them, again in perfect unison. They were mute at school, but not always quiet. Intense bursts of physical fighting could erupt between them seemingly with little warning. By the age of eight, the twins had stopped communicating with the outside world.

The film was screened at the Cannes IFF in the Un Certain Regard Section. At the Polish Film Festival, the film won the Best Film Award and Best Production Design and Score Award, moreover actresses Letitia Wright and Tamara Lawrance won the British Independent Film Award.
