Poland, March 1981. Eleven-year-old Irek and his mum, Hanna, board a bus for a company trip to Budapest. It’s Irek’s first journey abroad — and his first without his dad. Tensions rise when he realises that the real reason Hanna chose to go on the trip is very different from what she told him. Their confrontation leaves Irek torn between his love for his mum and his loyalty to his dad.
