Una Sombra en la Oscuridad (“”) is a 1979 Spanish horror film directed by Argentinian Diego Santillán. The movie stars Javier Illain, Pilar Leonor, Isabel Pisano, Mariano Vidal Molina and Emilio Álvarez.
Saul (Molina) is the master of a small fishing village and all of its inhabitants work under his command. Already a mature man exceeded fifty, Saul lives with his son (Alvarez) and decides it is time to hook up with a female partner to take care of him and his house. He, therefore, proposes marriage to Elena (Pisano), a prostitute he frequents on visits to the city. Elena agrees.
However, due to her new husband’s long absences, Elena strikes up a close physical relationship with his son. Meanwhile, the inevitable gossip begins in the village…
According to Spanish-language web blog Giallo Malastrana, this thoroughly obscure production aims at suspense but apparently ends up like a cheesy erotic thriller that showcases Isabel Pisano’s body. It has an ending that echoes Tod Browning’s Freaks (1932).
