Danny Lopez is new in town. He made a mistake back home in Las Vegas, and now he has landed at an experimental school in Colorado for "tough cases." At the Cobalt Charter School, everything is scripted-what the teachers say, what the students reply-and no other speaking is allowed. This supercontrolled environment gives kids a second chance to make something of themselves. But with few freedoms, the students become sitting ducks for a killer determined to "clean up" Colorado Springs.
