Summary: Sharing the same title as Martin Scorcese's first film, indie revenge saga Who's That Knocking on My Door? is the feature-length debut of up-and-coming writer-director Yang Hae-hoon, whose previous short film My Dear Rosetta competed at the 60th Cannes Film Festival. Garnering rave reviews at the 2007 Pusan Film Festival, this intriguing film revolves around five lonely urban souls driven to unpredictable extremes by alienation, trauma, and the jostle for revenge. Another outstanding entry from Korea's vibrant indie filmmaking sector, Who's That Knocking on My Door? features a fresh and talented ensemble cast led by Lim Ji-gyoo who also starred in Milky Way Liberation Front.

Loner Je Hwi begins to open up after starting an awkward romance with a mousy girl whom he meets rather serendipitously. There are more chance encounters to come as he soon runs into former classmates Pyo and Rom. Je Hwi actually holds a deep grudge against Pyo and Rom who bullied him in high school. Feigning friendship, he begins to plot his revenge with the help of a weird guy he meets on the Internet, but events soon escalate violently out of control.
