"Blue Gate") is South Korean director Kim Ki-duk's third film, released in 1998.
It was released domestically in October 1998, and screened at the Berlin International Film Festival in February 1999.
Jin-a (Lee Ji-eun), a 22-year-old prostitute, arrives at a small seaside motel called the Birdcage Inn to replace the previous one.
The son, Hyun-woo (Ahn Jae-mo), begs to be allowed to take naked pictures of Jin-a for a photo contest and to have sex with her.
Though Birdcage Inn was not successful in the director's native country, South Korea, it was his first film which succeeded in attracting international attention.
