Night of the Seagulls

The film starts in medieval times, when a young couple is attacked by the Knights Templar. The man is instantly killed, and the woman is carried away to the Templars' castle, where she is sacrificed.

The story then continues in the 20th century. Doctor Henry Stein (Víctor Petit) and his wife Joan (María Kosti) are moving into a very primitive coastal town, where they are met with distrust and hatred from the locals.

It does not take long before the doctor and his wife find out that the town harbors an ancient evil: Every seven years, undead Templars ride from the sea for seven consecutive nights to demand the sacrifice of a young maiden. The doctor and his wife then try to save one of the maidens, Lucy (Sandra Mozarowsky), from her horrible fate, aided by the local village idiot, Teddy (José Antonio Calvo).
