Hilarious and outgoing, Brittany Forgler, is everybody’s best friend ― except her own. Her partying, underemployment and toxic relationships are catching up with her. She receives a startling wake-up call when a visit to the doctor reveals how unhealthy she is. Motivated to lose weight, but too broke for a gym and too proud to ask for help, Brit is at a loss, until her neighbor pushes her to run one sweaty block. Soon, she sets an almost unthinkable goal: the New York City Marathon.

An isolated young woman uses her vibrator compulsively — until it starts deforming her body in disturbing ways. To regain control and change the way she masturbates, she goes on a journey through a lurid underground of corporate neurologists and orgasm gurus, none of whom seem to have her best interests in mind. Ultimately, there’s little she can do to withstand her vibrator’s eerie influence.

As a boy copes with his difficult home life and his parents' failing marriage, a mysterious girl suddenly appears. Faith, family and a special kind of magic come together as his new friend teaches them all about love, forgiveness and healing.
