Sgt. Platt (Amy Morton) returns from her honeymoon feeling like a new woman on Wednesday's episode of Chicago P.D.

And after a blissful week in the Wisconsin Dells ("God's country") with Mouch (Christian Stolte), Platt has no desire to return to the gritty world of police work involving assault, drugs, and in this week's case, a baby left abandoned by the lakefront.

"I am in a mood the likes of which have not been seen since 1997," Platt tells Lindsay (Sophia Bush) in the exclusive clip above.

Looks like it'll be up to Voight (Jason Beghe) and Ruzek (Patrick John Flueger) to track down the culprit.

Chicago P.D. airs Wednesdays at 10/9c on NBC.
