The smuggler's house stands out among the brambles of the forest, on the border between Belgium and Holland. Locals say it was the home of one of the most ruthless and meticulous butter smugglers in the entire area. He worked alone because he didn't trust anyone: only his lame son helped him.
A terrible secret hovers over the house, a murder weapon is hidden among the vegetation. It's up to Ole, a newly arrived boy, to unravel the secret. A boy who has just discovered he has a grandfather, or rather he had one, before he died a few days earlier.
