What a Honeymoon (1980)

Sinopsis: 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.)
