Backup’s on its way! In The Rookie starring Castle’s Nathan Fillion, 40-year-old construction worker John Nolan — thrown by divorce and an alarming encounter with some bank robbers — decides to join the Los Angeles Police Department.

Along with two younger guns, he’s assigned to the busy (fictional) Mid-Wilshire Station, and “they’re going through the fire together,” says creator Alexi Hawley. “I consider them the Three Amigos.”

Below, meet the newbies.

The Scion

Jackson West (Titus Makin) comes in full of eagerness and entitlement — no surprise, considering his dad is an Internal Affairs honcho. “Jackson grew up in a police household, gearing up to be a cop his entire life,” says Hawley, “so he thinks he’s the best prepared rookie in the history of the LAPD.” Of course, that’s a setup for some rude awakenings, which likely won’t please the senior West.

THE ROOKIE - "Pilot" - Starting over isn't easy, especially for small-town guy John Nolan who, after a life-altering incident, is pursuing his dream of being a police officer, on the premiere episode of "The Rookie," airing TUESDAY, OCT. 16 (10:00-11:00 p.m. EDT), on The ABC Television Network.

The Hotshot

Carjackers, beware: Lucy Chen (Melissa O’Neil, Syfy’s Dark Matter) can trip ’em, grab ’em and cuff ’em like that. But she’s also got some hurdles lying ahead. For one, her training officer, Tim Bradford (Eric Winter), tests her with mean mind games “that keep her off balance,” says Hawley. And, don’t tell the squad, but she has feelings for one of her fellow rookies. What a relief to know both of her parents are therapists!
