One night, groggy American expat George finds himself tending to an injured crane that bizarrely appears in his London backyard. The next morning, Kumiko — a quiet, independent woman — soars into George’s life. She vaguely reminds him of the crane and leaves him wondering whether he was dreaming. As if in a storybook, Kumiko brings opportunity, human interaction and love to the lonely man but remains an enigma. George’s yearning to know more about her threatens their relationship and endangers their lives.
