Let me write up a review of this 1973 nunsploitation film.....
First off, the DVD quality was good, and Redemption Films is getting a good rep at quality releases of really sleazy B movies. "The Sinful Nuns of St. Valentine" is a prime example of their fare. And the redemption flms short at the front may have been better than the movie.
"SNoSV" starts off with a man in white on horseback, being chased by some guardsman. He's unhorsed, having been shot in the arm, and gets into a swordfight with the guards. After one of the more pitful sword fights I've seen on film, he's victorious. He flees into a local convent, St. Valentine, where it just so happens the groundskeeper knows him.
Seems our hero, Esteban, has been framed for killing a bishop, and has been declared a murderer and a heretic. And it just so happens that the convent happens to have his beloved, Lucita, who was placed there by her father in punishment for wanting to marry Esteban. How lucky. Anyway, Esteban is hidden away to recover from his wound, (though he never seems to get a clean shirt, because he wears the same torn shirt with a bright red bloodstain for half the freaking movie.)
After finding out that her beloved is there, and checking on his safety, Lucita goes back to her cell, to find another novice keeping her bed warm. The naked novice, Josefa, does her best to seduce Lucita, but Lucita resists her attempt and lies there, still and unmoving.
The next day, we're treated to the senior nuns whipping a topless nun for some unspecified transgression. Josefa seems to get off on watching the Abbess whipping the other nun, as the Mother Superior later asks her to report to her for special counciling. Josefa later sees the Abbess, runs into her arms - and is rather unconvincingly stabbed to death.
