When I Was a Partisan (2008)

The film centers on Lithuanian partisan resistance. An actor portraying a partisan in a play titled "Bunker" has a hallucination during a performance, leading him to believe he is a boy from post-war Lithuania. In 1948, this boy made an error that resulted in his own death and the death of a partisan's wife. Back in the 21st century, the actor is given an opportunity to correct that past mistake.
