Tune into NBC next week for the season finale of "Chicago P.D."

"Lindsay (Sophia Bush) struggles to stay clean in the season finale of Chicago PD, Season 2 'Born Into Bad News' airing next Wednesday on NBC," the SpoilersGuide description reads.

In the promo for next week's episode, Lindsay is seen at a bar drinking uncontrollably. An officer says to her, "So you're back at your old habits again."

She then responds to a crime scene where it seems like she may have accidentally shot a victim. "Watch as her addiction spirals out of control," the voice over says.

Lindsay partner calls for back up saying that shots have been fired and a reporter is down.

In the last episode, "Push the Pain Away," Lindsay slipped back into her old ways while dealing with the death of her good friend Nadia, TVFanatic notes.

She blames herself for her friend's death and continues to put herself down. In one scene, she doesn't try her best to catch a suspect. She even lets Nick capture her and tells him to shoot her.

Lindsay also links up with a friend from the past who is into drugs. There were drugs on the table when they were together although there were no scenes of her taking them. She is going to have to get help quickly before she loses her job or her life.

Last week's case for "Chicago P.D." involved a family who went around killing people because their loved one was killed by toxic waste that was put into water by Lancaster Chemical.

P.D.'s season finale will focus on Lindsay's addiction. Will she get help for her bad habits? Or will she continue to spiral downward?

Tune into NBC Wednesday at 10 p.m. to see the season finale of "Chicago P.D." to find out.
