A group of musicians discovers a decapitated head in the air vent of the derelict hotel room they are staying in. That same night, they are confronted by the spirit of a dead prostitute. They must solve the mystery of her murder before they are killed.
The Sisters is the epitome of a stereotypical horror film. However, what makes it exceptional and a must-watch is its foundation on a real and unsolved murder case in southern Thailand in 1991.
It is a matter of public record that each member of the unfortunate group that found the body died mysteriously one by one, rendering the case infamous. These baffling deaths have spawned many an urban legend.
The film's low-budget and dated production is a flaw that works for it. It creates a realistic, gripping atmosphere that can make you wet your pants.
