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.
