Brief Plot


Cahill spots the shooter.

A misguided youth shoots his pellet gun onto the highway and causes an accident when he hits a passing car. Ponch and Jon assist with the accident. The ambulance driver speeds with the concussion victim off like a nut while Ponch and Jon investigate the scene of the crime. Later, the kid calls the hospital asking about the woman's condition. He's obviously upset about the whole thing. When Ponch and Jon arrive at Valley General Hospital to do their follow-up, they end up chasing a speeder. When they pull it over, we learn it's the ambulance driver. Before the briefing, everyone's entering a lottery about how long it will take Jon to rope a steer. When the kid goes back to get his gun, Sindy spots him and calls Ponch and Jon. He brings the gun to his friend, the gun dealer. When he leaves the store, Ponch chases him on foot. Jon cuts him off and catches him. After talking things over at Central, Jon and Ponch take him out to a ranch to ride. Jon shows off and then lets the kid ride. Meanwhile, the ambulance driver is fired from his job. When he leaves the hospital, he tells his wife that he still has his job. Later, Jon and Ponch introduce the kid to the un-injured accident victim. She begins to like him. Later, Ponch and Jon chase the ex-ambulance driver in a stolen ambulance full of dynamite. The ambulance stops in a playground and kids start picking up the dynamite while Ponch and Jon chase the driver. After they catch the driver, all three of them run to the dynamite and convince the kids to hand it over. At the end, everyone's enjoying Jon in the mini-rodeo.

Great Quote

"Ponch, you're a dirty, double-crossing fink. That's the kid that caused the accident, isn't it?"

Someone moved the pellets!
  • When the kid with the gun takes off, he drops his tin of pellets. A number of them fall out. When Jon discovers the tin of pellets later, the tin is nearly full and the lid is much closer to the tin. It looks neatly placed.
  • When Ponch and Jon chase the ambulance driver, both the driver and the CHP exit through a gate, pass a pillar, a speed limit sign, and a smaller sign. The next shots appear to be the same footage given where they pass and the movements of the CHP riders. The first shots of the driver and then the CHP officers appear to be edited versions of the second shots.
Visible jump ramp
  • During the chase of the ambulance driver, a jump ramp is visible right before one vehicle vaults another (853 LKQ).
  • The kid, Barry, shouts "I killed her, didn't I?" when Jon catches him. How does he know that only one woman was hurt? How could he be sure the passenger was a woman from his distance? Why didn't he say, "I killed them, didn't I?"
  • Does Jon usually go riding with criminals?
  • A doctor is the ambulance driver's boss? Aren't ambulances run by private companies or at least someone that's not busy being a doctor?
