The Lindemanns are the German owners of the relatively small family run Hotel Paradies on the island of Mallorca. Their rival Kroll, wealthy owner of a nearby luxury hotel, sabotages their business in an effort to force them into selling the place to him.
The young son of new hotel guests is jealous because his mother only pays attention to her new boyfriend, an enthusiastic diver on the search of sunken treasure finds a dead body in a shipwreck, Max Lindeman makes preparations for an anniversary party and the new hotel manager seems to be paying a little too much attention to hotel owner Lisa Lindemann and her paintings.
