The Search Adam-12 : Season 4 Episode 5

1-Adam-12 is back after routine maintenance, but the radio is having problems communicating with Central. During a robbery involving two suspects, Reed captures one while Malloy takes off in pursuit of the other one through a park, but Malloy loses control of the car and it rolls into an embankment, hidden from the road, and the officer suffers internal injuries and a broken leg. All available units are called in to search for Malloy, who has to watch helplessly while a murder suspect comes out and take his shotgun (which Malloy was using for a splint) and sidearm, and rips out the radio mike only leaving the wires. Malloy uses the wires to send signal for help, which Reed picks up and rescues his partner.
