Amir leads a lonely life. With his dog for sole company, he drives through the underworld of Tehran, dealing drugs of all kinds and healing troubled souls like a modern prophet. He navigates the city streets aimlessly, following the directions of his GPS while getting high to escape a town with no future. And yet, in his wandering he will find the seed of resistance.

Young Iranian director Ali Ahmadzadeh's “Critical Zone” won the Golden Leopard for Best Film at this year’s Locarno Film Festival.
