Merry Christmas.

Hyun-tae, who is a wild goose daddy, is going to the sea to commit suicide on Christmas Eve. At the same day, Kaka who's working at an auto shop is gone to the sea by his boss. Hyun-tae and Kaka don't meet each other, but they connect through Mi-joo, Hyun-tae's daughter. It’s an itinerary of fathers’ Christmas Eve, which look different but the same.
