A serpent, created by radioactivity, threatens a Spanish coastal town.

Medieval soldier of fortune Ettore is travelling through Europe with his partners looking for fight where they can earn some money. When they come across a Spanish castle under siege by the French army, Ettore first bides his time to determine which side is the winning one (and thus more likely to pay his fee).

Somehow, Ettore must rally the weakened Spanish troops to battle their enemy long enough for reinforcements to arrive.

Emilio Antunez and his wife Charo, come to La Molina, willing to spend a few happy days of vacation.

Arturo, who has just turned 15, is in love with 13-year-old Paloma. In a moment of passion at a ski lodge while on a field trip to the mountains with their schoolmates, he gets her pregnant. Afraid of what may happen to them if their strict (but somewhat inattentive) parents or any of the rather straight-laced teachers at their Catholic school find out about the baby, Arturo and Paloma turn to their young friends and relatives for help instead. This proves to be something of a coming-of-age for everyone involved as they try to help the young couple get married, conceal the pregnancy from their parents, and prepare for the birth. The many adventures they have while doing this, while often amusing, help drive home to them that the old wives' tale about storks bringing babies is just a myth (hence the title), and pregnancy and childbirth are actually very serious matters.

Also released as Valley of the Swords, this lugubrious US/Spanish co-production features the usual mid-1960s "tax shelter" international cast. Broderick Crawford plays a despotic 10th century Spanish king who, in cahoots with the invading Moors, has banished handsome Castilian nobleman Spartaco Santoni. With the surreptitious aid of Crawford's daughter Teresa Velasquez, Santoni assembles an army to march against the Moors. In keeping with the 13th century epic poem from which this film was derived ("El Poema de Fernan Gonzales") Santoni's path is smoothed by the celestial intervention of patron saints Milan and Santiago. Among the big names picking up a few tax-free dollars in The Castilian are Cesar Romero, Linda Darnell, Alida Valli and Fernando Rey.
