As a twenty-four year-old white female teacher with predominately black students in Memphis, Tennessee in March, 1968, Sam is presented with three obstacles. First, he must find a way to hold the attention of his students, allowing them to pass the exams. Second, in doing this he can turn around the life of the teacher he has leaped into so that she takes the correct career path. And third, he is in a position to save the life of Dr. Martin Luther King, Jr. just days before his assassination - but is Sam really there to save him?
