One of the most tired plots on every cop drama ever made is the rookie plot. Some newbie comes on the job, and some smug, hard-bitten veteran inevitably shows this “Bambi’’ the ways of the street. Rookie mistakes are made, lessons are learned, first days are finished with whiskey shots at the local bar.
The brilliant idea behind ABC’s new cop drama “Rookie Blue’’ is to give us the rookie plot over and over again, all summer long. The series, which premieres tonight at 9 on Channel 5, follows five newbies as they hit the beat and get tangled up in shootings, overdoses, and domestic squabbles. They are as earnest and green as they are pretty, as they struggle to get comfortable carrying guns and shouting commands into car radios. But we know they have guts underneath their spotless uniforms, and — spoiler alert — we know they’re going to make it after all.
