In the spirit of films such as "Last House on the Left" and "Day of the Woman" aka "I Spit on Your Grave" , "El Perdido" follows the storyline of most rape revenge horror films.
A woman awakens on an island. She has no clue how she has gotten there, nor does she remember her own name. The little that she does know is that she does not have any natural instinct for being alone in the woods, or for being by herself.
The first of the horrors that she encounters is an all female coven of vampires. Unable to defend herself, Lost flees further into the woods, takes another fall, and is found unconscious by a coupled of farm hands who try to take advantage of her and fortunately fail.
Too bad her somewhat good luck is about to run out.
The farmhands return the new find, to their cabin headed by the cruel and savage, drug lord, Craven. Craven sees everything and anyone as his possessions to do with what he wants and unfortunately for Lost, she is his new plaything. After countless incidents of brutalization, Lost is able to flee the cabin, only to end up in the arms of a vampires embrace.
The coven that she so feared before gives her the strength and will to take her revenge upon Craven and his workers and to finally find peace for herself.
