Cuando acecha la maldad.
When brothers Pedro and Jaime hear gunshots in the woods at night, they suspect some dodgy ******** is afoot in their sleepy Argentinian village. The next morning they discover a half eaten corpse.
Their investigation leads them to the house of María, who explains that Uriel—bloated, bedridden, and covered in weeping sores—is possessed by a demon.
After a failed attempt to seek help from the the local police (who curiously show no interest) the brothers visit Ruiz, who helps them to dump Uriel's visibly rotting body—still very much alive, despite the odds—on a deserted highway several hours from the village.
It turns out that this was not a good idea after all, and everything gets very much worse, very quickly.
Cuando acecha la maldad is a fine example of the aggressive cinematography we've come to expect from Mariano Suárez, blended with the famously eccentric directorial choices of Demián Rugna. I must confess to some skepticism when I saw Luis Ziembrowski(!?) cast alongside Lucrecia Nirón Talazac(?!) but I'm delighted to admit they both proved me wrong in the best possible way.
If you're looking for a solid Argentinian horror, this is definitely one for you.
I rate Cuando acecha la maldad at 24.97 on the Haglee Scale, which works out as a robust 7.5 on IMDB.
