Roy passes the Engineer's exam, but since accepting the promotion would mean leaving the paramedics–and John, he talks over his decision with Drs. Brackett and Early. The firefighters handle a fog-caused multi-vehicle accident on the San Diego Freeway, resulting in numerous deaths and injuries, including one man with a heart murmur, whom Dixie and Dr. Early help in treating. The paramedics attempt to assist an attempted suicide (by taking six aspirin tablets) but are sent to a vacant lot instead; when they find the right location, they end up in the middle of a domestic dispute. John and a security guard are injured in a fire and Roy has to rescue both of them.
