Based on the popular conman character of Kim Seon-dal from Korean folktale, the movie follows Seondal (Yoo Seung-Ho) when he deceives the wealthy and powerful and sells a river.
It doesn't really push any boundaries, but the characters are fun to watch - Yoo in particular plays Inhong in full on charming-rogue mode, and pulls it off. The plot may involve a swindle, but the film itself delivers a modest return on investment.
