NYC 22 -- a gritty look at the lives of rookie cops in Manhattan -- introduced America to a sublime sextet of stars in last week's premiere, and tonight is your chance to check out a thrilling new episode.

Titled Firebomb, the rookies are each faced with another seemingly insurmountable hurdle while patrolling the streets -- but for Harper and Sanchez, their assignment puts them both in the line of fire when the titular explosion rocks a city block.

Watch an exclusive ETOnline sneak peek and tune in to NYC 22 tonight at 10 p.m. on CBS.
