Sommer (1986)

A father and son travel together to the seclusion of a village in the mountains. There, the father tries—tirelessly, stubbornly, lovingly—to enter the mysterious world of his mute, autistic son. A world of rituals, of incomprehensibilities, of the child’s gaze into the infinity of a glass marble. A world of refusal. The father tries to break through the child’s seclusion, but the child’s isolation begins to spread to him. Waiting and silence, and the attempt to learn something about the child. Time stands still.
