Istvan Szab - Apa AKA Father (1966)

Against the backdrop of post-WWII Hungary, the young orphaned boy, Tako, needs to create a loving fabrication for his long-lost father who died prematurely in Nazi-occupied Budapest. Having only faint and disappointingly few memories of his parent and hero--while still struggling to distinguish reality from fantasy--a grown-up Tako embarks on a journey of truth and enlightenment, as he attempts to unearth the identity of the beloved deceased he barely knew. Now, little by little, childhood's wide-eyed innocence gives way to the inescapable certainty. In the end, who was the man Tako called dad?
