Twin brothers separated at birth grow up worlds apart. Mohamed, raised in Assyut, Egypt, as a devotee of fundamentalist Islam, comes to Paulo Alto, California, to find he has a twin brother, Matthew, he didn't even know existed. Worse, his brother is a Christian and is about to marry the girl he once loved. Within three weeks, Mohamed's militant group plans to bring the United States to its knees, but the operation will destroy both his brother and the woman he believes should rightfully be his.
