Can't remember that film's name? Post the plot, and see if other users can help.
There are two boys, one of them is foreign (French maybe?). They are both teenagers and they are staying in a cabin over the summer. One of the boys' dad's past away and he left a record that is worth a lot of money. He tries to find the record before the maid does. I think the movie has the word "Lake" in it's title and is named after the record.
