Based on the lives of June and Jennifer Gibbons, real-life identical twins who grew up in Wales and became known as "the silent twins" because of their refusal to communicate with anyone but each other.

A physically perfect but innocent man goes in search of his long-lost twin brother, who is short, a womanizer, and small-time crook.

After ten years of estrangement, twins Maggie and Milo coincidentally cheat death on the same day, prompting them to reunite and confront how their lives went so wrong. As the twins' reunion reinvigorates them both, they realize that the key to fixing their lives just may lie in fixing their relationship with each other.
