A hiker leads intelligence to a young woman being held captive in the woods near Chicago, and a former relationship of Halstead's comes back into the picture, much to the surprise of Lindsay.

While Jody and Sheila comfort a dying Grammy, Frank steps out and stops at the Kash and Grab, where he walks in on Ian and Mickey in a compromising position.

Jasmine throws an end-of-summer blowout and invites Fiona down to David's boat but neglects to inform her that Steve and Estefania will also be on board.

Monica blows back into town and immediately hooks up with Frank for more shenanigans, but the kids are left wondering if she's finally here to stay, and Frank is eager to pick up the ashes of his late mother and reclaim the cash he believes she's hidden.

With Monica around and pitching in, Fiona is able to devote more time to pursuing her GED and a promotion at the club.

Fiona has second thoughts about loaning money to Meg; and a drunken Frank staggers home, where no one wants him, until he proves he can quiet fussy Baby Hymie.
