Emerson Graham's nights as a cab driver are filled with annoyances and inconveniences, but until tonight, never attacks and disappearances. After picking up a mysterious passenger her evening goes from working a job to performing a quest as they must race against the clock to defeat a force of evil. The meter is running.
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. Written by Sundance Film Festival
