On the Third Day

The name of this movie is On the Third Day released in 1983-01-01 and it's main theme is A headmaster and his wife return home to find one of their doors to have part of a window pane neatly cut. Looking through the house for whatever might be missing, they find a young man sitting in one of their rooms, and the phone isn't working. The man's behaviour is strange, but polite. He says he's arrived from Australia and was friends there with an old friend of the headmaster. He proves to have a lot of personal knowledge about the family, so his story seems to be true. However, he definitely has a dark side, doing over-the-top practical jokes, producing a gun, engaging in a particularly bloody boxing match. IMDB.
