Now recovering from a gunshot wound and feeling the effects of his age, John and the team welcome two new rookies and continue the hunt for two dangerous inmates with very personal vendettas following their prison escape.

The team is tasked with community policing while hunting for a local vigilante. Meanwhile, Celina’s instincts are tested, and Tim and Lucy discover secrets about the two new rookies.

Ahead of Bailey's return home, John looks for clues to locate Jason Wyler. Then, Tim and Lucy swap rookies; a friendly face resurfaces at the station, and Wesley feels unsettled over Angela.

It’s Valentine’s Day, and Lieutenant Grey gives Tim and Lucy an unromantic assignment, while John and Celina track down a missing girl. Later, the team sharpens up for a charity gala where multiple relationships come to a head.
