La rana verde (1960)

In Cimera de los Infantes, a peaceful and imaginary Castilian town, the youngsters are bored because they hardly have fun to vent the ardor of their youth. That's why they meet every day in a bar called The green frog, where, between games of dominoes, they plan to seduce girls from wealthy families who stay during the summer in a residence located in the town's castle.
