The Resonance Principle (2022)

Introverted and edgy, the Romanian backpacker ANDREY (29) travels on his way back to home on board of a regional train somewhere in the Bulgarian province. When the convoy breaks down in the middle of nowhere, the growing discontent among the passengers creates an electrified and tense atmosphere. Suddenly, a frightened elderly woman sparks the terror in the coach by pointing her finger at Andrey accusing him of being a terrorist who wants to kill them all with the bomb in his suspicious backpack. Inexorably, the avalanche of fear invades the whole coach and smashes both physically and psychologically the incredulous Andrey.
