Graves are never silent, especially not if someone continues to put flowers on it 60 years after what was officially an accidental death, so naturally someone has to start digging about it, in this case a young enthusiast for noir films whose wife is expecting their first baby, while his interest in digging about the grave risks his marriage and family, since his wife just can't put up with competition from a grave that is not silent. Naturally he has to finish the job and keep digging even when threatened and beaten up by thugs, and finally gets some help by someone who has kept silent for too many years (60), and that's where the film becomes interesting. The first hour is a lost hour, nothing happens, while the last hour at last presents a case. As so often in such cases, when you get to know too much, it's no idea pushing it on any further, especially if your young wife will have that baby and you want to keep your family. Enough is enough.
