The legendary Loreley has been living for centuries in a grotto beneath the river Rhein in Germany. Every night when the moon is full, she turns into a reptile-like creature craving for human blood. When one girl after another of a nearby boarding school is killed by her, a hunter named Sigurd is engaged to kill the monster.
Mortadelo (Mort) and Filemón (Phil) are visited by Professor Chiflágoras, Filemón's crazy cousin, who has invented a time travel machine in the shape of a closet. (Seven animated shorts with a common narrative: The Time Closet; In Waterloo; The Yeti; Incredible Mission; The Impostors; Count Macula; Maxi-adventure at Sea.)
Two newlyweds, Yolanda, an adventurer, and Simón, a young bookworm, travel to Banana Island, where they enjoy the days of wine and roses of their honeymoon until a particularly ridiculous dying man gives them a simple scrap of paper, thus putting into motion a crazy treasure hunt, as fun and erotic as it is dangerous. (Filmed in 1979, lost around January 1980 and found by chance in 2018, in the vaults of the Spanish Film Archive.)
