The Bothersome Man（2006）

Forty-year-old Andreas arrives in a strange city with no memory of how he got there. He is presented with a job, an apartment - even a wife. But before long, Andreas notices that something is wrong. Andreas makes an attempt to escape the city, but he discovers there's no way out. Andreas meets Hugo, who has found a crack in a wall in his cellar. Beautiful music streams out from the crack. Maybe it leads to "the other side"? A new plan for escape is hatched.
