Action-filled entry, especially with the copter. Then too, Crawford gets a workout climbing in and out (I hope he liked copters !). Story picks up midway in the kidnapping of son (Roy) of wealthy father. The two kidnappers are keeping him in a rundown shack in the boondocks. Trouble is a game warden figures out who they are and notifies the Patrol. Soon a standoff develops with cops and wounded Roy on outside and kidnappers on inside.
I believe HP was either first or one of first TV series to use copters regularly in law enforcement. Here we get a good look at a two-man version, and note how the stretcher is ferried. Anyway, director Landers does good job with close-ups at right time. I'm not sure, however, how the crooks thought they would escape once they lost their hostage. Then too, it's typical Hollywood shootout where fusillades are fired but hardly anyone gets hit, even when standing behind porous bushes. But that's just carping, when the real draw is action with the copter and Mathews racing about the sticks in his business suit.
