The parallel stories of two ordinary women - one, a single mother barely supporting her handicapped son, and the other, a working mom precariously balancing her family with a high-pressure career - on one extraordinary day. Each woman's life frays under the weight of her circumstances and spirals out of control. As police officers race to save them, pieces of a shattered puzzle fall into place - maybe this wasn't just a tragic car accident after all. Both women fight for their lives, but ultimately, only one will survive.
