A young man is left adrift in the country when his friends who were supposed to meet him, to help him get over a breakup, fail to show. After showing up at the wrong "hotel" a nightmarish "after hours style" journey begins. A lot of drinking, being drugged, left stranded in his underwear and a friends's possible betrayal are just some of the problems to overcome. Regardless of other comments: never boring.
It took me about a week to get through this film. Whenever I got bored I switched it off. However, my determination to finish something I've started eventually got me to the end, that is the disappointing "apropos" ending mentioned below. I appreciated some of the bleak moments of contemplation... but there was no real growth or realization for hyeok-jin. Overal disappointing.
