Overview: 1-Adam-12 is back on the streets after routine maintenance, but the radio isn't working properly. During an armed robbery involving two suspects, Reed captures one while Malloy takes off in pursuit of the other one through Griffith Park and loses control of the car, and it rolls into an embankment hidden from the road, with Malloy suffering severe internal bleeding and a broken leg. All available units are called in to search for Malloy, who has to watch helplessly while a suspect hiding in the park takes his shotgun (which Malloy was using as a splint for his leg) and sidearm, and tears off the radio microphone leaving only leaving the wires. Malloy uses the wires to send a signal for help, which Reed picks up and is able to rescue his partner.
