The Bare-Breasted Countess) is a horror film written, directed, and co-edited by Jesús Franco.

[2] The film is set in Madeira and stars actress Lina Romay as Irina von Karlstein, a vampire who has sex with both male and female victims.

In an unusual variation of the vampire myth, Karlstein performs oral sex on her victims until they die, draining them of their sexual fluids.

The plot revolves around Countess Irina von Karlstein (Lina Romay), a mute woman who needs sex like a vampire needs blood in order to stay alive.

When new victims are found fatally drained of potency, and left scattered around the town, forensic scientist Dr. Roberts consults his colleague, Dr. Orloff, who confirms that a vampire is responsible.

The countess is also confronted by a psychic investigator who believes he is destined to become her lover and join her among the immortals.

[3] Romay was more open about her sexuality than Miranda, which allowed Franco to focus on his more sex-based themes in his films.

[6] The film was edited by Franco and Ramon Ardid (Lina Romay's then-husband) under the combined pseudonym Pierre Querut.
