What’s the Story About?
Set on a long-abandoned island in the 1960s, “Modup” follows a group of characters whose lives become entangled like an unsolvable knot. The mystery unfolds as an outsider’s arrival on the isolated island sets off a chain of unpredictable, unsettling events for the people who call it home.
Meet the Cast
Yoo Hae Jin plays Lee Do, the village chief of a small fishing community who protects and watches over the isolated island. Sharing his excitement, Yoo Hae Jin noted that filming begins in September as the weather starts to cool, and expressed hope for a safe and successful shoot.

Yim Si Wan takes on the role of Sang Gun, Lee Do’s determined son who charges ahead once he sets his mind to something. At the request of Seon Ok, he travels to the remote island despite his father’s strong opposition.
Kim So Hyun stars as Seon Ok, marking her return to the big screen for the first time in roughly a decade. Her character travels to the island searching for a cure to an illness with no clear cause, and her arrival ends up pulling Lee Do and Sang Gun into the unfolding mystery.
Lee Moo Saeng rounds out the main cast as Gu Taek, Seon Ok’s father, who journeys to the island as a last resort to save his ailing daughter.
