Remember that urban legend about getting drugged in a bar and then waking up in a tub of ice with one of your kidneys missing? Well, Hong Kong’s Lo Chi-Leung has made it into an intense, twisted horror film. Ching, the lead woman character, has a bum kidney, she’s in renal failure which causes her to be underweight and frequently and unexpectedly throw up (and often on someone). Her boyfriend Wai appears to be having an affair with the other woman character, Ling. Tying all three together, besides the affair, is a spooky guy who appears to be the one stealing kidneys from unsuspecting women.

While at times the tension is stressed and obvious, the creepiness of the symbiotic and parasitic psychological ménage à trois is well worth the price of entry, especially if it comes back on the Sundance Channel and you can just tape it. It’s part of the Asia Extreme series that airs late Sunday evening (12 AM Monday morning).
