On 26 October 1979, the president of South Korea was assassinated. The man behind the barrel was the president's own chief of the secret service, KCIA boss Kim. In this rambunctious and burlesque film, Im Sang-soo portrays the last day of the president's 18-year reign, focusing on the president's tawdry evening entertainment with his cronies… but, hey, no fun before a lecture on discipline and the evils of democracy. Im assembles a top brass cast for his depiction of political carnage, which featured in Directors' Fortnight in this year's Cannes Film Festival.

GrodsCorp says:

Cracker of a film mixes black comedy with a history lesson. President gets bang from a gun while getting liquored up in readiness for a bang from a hooker. Incompetent people run around everywhere and eat noodles. Rolicking good time.
