Ketnet's heroes can't stop stunting. Not even during their adventurous holiday at the Belgian seaside. The first step? Transforming their residence in the dunes into a miniature theme park, including a thrilling roller coaster. Now they're all set for the summer of a lifetime. Especially Dempsey, who has fallen in love with Eva, a girl that's also on holiday. But their romance won't last long. Eva has to depart on a trip to England, where's she's enrolled in a language camp. The heroes want to comfort Dempsey and decide to go after her. The plan? Crossing the sea in boats they've made themselves. But after departure, not everything goes according to plan.—Hotel Hungaria

Dempsey oversleeps, so he must race a daring parkour route to be just in time at the railway station, where Dempsey's heavy backpack nearly prevents him from boarding the train to the North Sea for two months coastal holiday. While Sieg confidently shows off his dating weapon, a glorious six-pack, they are bluntly approached by shameless Antwerp hag Lea, whose interest in the 'hot pony' isn't desirable, unlike her foxy cousin Eva, exactly to Dempsey's taste, but she's bound to a language course across the English Channel after a single day. The quartet finds the 'beach house' Sieg arranged a wobbly shack, but 'rebuild' it as a death-ride. Having met old former Channel sailor Jos, given Dempsey's sighing for Eva, they decide to build their own boats each and sail to England. They all sink, but combined efforts should prove sea-worthy, so the love-birds may be reunited at Ramsgate.—KGF Vissers
