After a couple of years we meet Captain Zeppos again. Ariane has become his wife and Ben is studying in the city. When Captain Zeppos collects Ben in the city, they see a couple of men lugging a heavy box. There are some newcomers in Belder - first there is Aunt Cara, an eccentric old lady, living in the cottage at the 'Laar'. And there's Brems and his young son Frank. Captain Zeppos meets the boy Frank and takes him for a ride in his Amphibian car. Ben follows the lorry with the heavy box and makes an odd discovery.

Captain Zeppos sees Frank home in his amphibian car. At Frank's place, Ben and Captain Zeppos meet Hugo Brems, Frank's father. Ben thinks he recognises Brems as the man who was brought to Belder in a box. While horse riding in the woods Ariane meets some strange hunters. Brems leaves Belder while his son stays with Aunt Cara. One evening, Aunt Cara calls for Captain Zeppos's help.

The disguised hunters are after a painting: 'De Eglantier' ('The Wild Rose'). The painting is in Aunt Cara's possession - she was given it by Frank who got it from his father Hugo Brems. After a surprise attack by the hunters, Aunt Cara disappears. Ben guards the house and he discovers a hatch under the carpet. He finds several valuables there that were stolen from the church in Belder. The hunters catch Brems.

The hunters capture Ariane. Hugo Brems is locked away in the city. The gang wants to lure Captain Zeppos in a trap. They find out it isn't an easy thing to do. Meanwhile there's one question that remains: are Clovis and Aunt Cara partners in crime?
