Emergency!

The paramedics find a mechanic in a catatonic state injured in a vehicle fire at a garage, and the Rampart doctors are unable to determine the cause of his condition. While Dixie reaches a college graduate from San Francisco, Roy and John lecture a frequent caller on the dangers of constantly calling them because of her loneliness, then respond to a woman who had mixed ammonia with bleach and inhaled poisonous chloramine vapor. Paula Slayton returns to give John a Yorkie pup, keeping a promise made to him for caring for her dog while she was hospitalized; Boot and the pup engage in a wild chase around the fire station, resulting in Captain Stanley deciding the station can only have one mascot. The firefighters assist an elderly couple trapped in their home–by tumbleweeds. The catatonic patient receives an injection from his friend–and he responds by jumping out a window onto a ledge; he then almost kicks Roy off onto the parking lot until he is tranquilized.
