Suavidad Beach, a small provincial town in California. Jeffrey Coltrane and Amity, his eleven-year-old daughter, who live here, cannot survive the pain of loss - Michelle, Jeffrey's wife, has been missing for almost seven years. One day, a mysterious artifact of unknown purpose, the so-called “key of keys,” falls into their hands, and the lives of Jeffrey and Amity change dramatically. They come to their house with a search, they are pursued by strange people in black, trouble follows trouble, and, it would seem, there is no escape... That’s when the “key of keys” comes into play, opens the door to another for father and daughter peace, and, most importantly, they gain hope that Michelle will be found.
