To escape her dreary existence, Setsuko adopts a blonde wig and the alter ego of "Lucy," a free-spirited and confident version of herself. When John suddenly disappears, Setsuko follows a cryptic clue to California, embarking on a chaotic and poignant journey across Los Angeles.

Directed by Atsuko Hirayanagi, this touching film blends sharp humor with deep melancholy, exploring themes of identity, loneliness, and the desperate search for human connection in a world that often feels isolating.
