Martin Bohm (Kiefer Sutherland) lost his wife in the twin towers on 9-11. He used to be a newspaper journalist, but he's struggling with his life especially his autistic son Jake. Jake is a mute, but he seems to be doing something with numbers that is foretelling events that hasn't happened.
There is a high concept interesting idea, but it's a tiring show. Kiefer is ALWAYS out of breath, always chasing after the kid. It's all too repetitive. The other stories related to the main show are sometimes interesting. They don't always work and they don't really advance the main story. That's probably why that structure was eventually dropped. The second season was a feeble attempt to try to continue a failing show.
