On the outskirts of Austin, 10-year-old Annie tears around on her BMX bike, hurls dough at cars, and smashes things up with her baseball bat. Her father, a goat-farmer-cum-demolition-derby driver, does little parenting. Annie has no friends her age, so her daily routine is filled with solitary mischief. Playing in the woods one day, she hears a woman’s plaintive call for help from an abandoned well. Though Annie feels driven to visit the well daily, she is unsure about how to deal with the woman’s plight.

In the massive city of Tokyo, Kumiko, a twenty-nine year old, lives in utter solitude. She works a dreadful, dead-end job under an awful boss, is intimidated by her well-off peers, and nagged incessantly by her overbearing mother who is exasperated by the fact that her daughter is not married or even in a relationship. The only joys in her life come from a grainy VHS tape – an American film in which a man buries a satchel of money in the snowy Midwestern plains – and her beloved pet rabbit, Bunzo. Kumiko is somehow convinced that this treasure is real, and obsesses over its discovery. With a hand-stitched treasure map and a quixotic spirit, Kumiko embarks on an incredible journey over the Pacific and through the frozen Minnesota wilderness to uncover a purported fortune.
