Julia and Tobias seem to be the perfect couple. But behind the façade and designer kitchen, trouble is brewing. The fragile balance between the two is shattered when their daughter Marielle suddenly develops telepathic abilities, granting her the power to see and hear everything her parents do – day and night.
The couple soon realises that the lies they have been telling each other can no longer be hidden from Marielle. When their most uncomfortable secrets are exposed, Julia and Tobias engage in a manipulative game that leads to increasingly awkward and absurd situations which escalate the conflict and the consequences.
