When a construction worker takes a fall from the twelfth story at a construction site, Grissom is convinced the victim is electrocuted. But as the Sheriff and a lot of others have no trouble believing it's a suicide and the evidence doesn't immediately support his theory, he has to go to a lot of trouble to prove murder. Meanwhile Nick and Catherine look into the death of a teenage boy who apparently suffered an epileptic seizure during a therapy session.
