Begins when a man shipwrecked on a remote island with no memory discovers an old-fashioned mansion that does not fit the island. The story is about a man running away from the suspicious behavior of an unidentified family living in a mansion and threats to kill him, but as his memories gradually return, they conflict with each other to take over the island. Adapted from the webtoon "Pig Pen" (돼지우리) written by Kim Carnby (김 칸비) and illustrated by Cheon Beom Sik (천범식).
