Frank (William H. Macy) and his estranged wife Monica (Chloe Webb) are back in business in the upcoming episode of "Shameless."

In the episode titled "Ride or Die," the promo reveals that the ex-couple will team up to rob a bank. Monica arrived in town last episode to force herself on her family once again. At first, Frank wanted nothing to do with her and did his best to avoid her. Old habits die hard though, and soon enough, the Gallaghers were chatting like old friends.

Now that they are back in business, their first crazy mission is to get their hands on some money. Unfortunately, their plan to rob a bank will turn into a complete disaster.

As per the clip, Frank and Monica will charge inside the place showing off their guns. For safety purposes, they will not forget to wear masks. When the woman behind the desk refuses to budge, Frank then discovers that she is conveniently safe behind bulletproof glass. The thief can only express his anger over such a ridiculous situation. Frank and Monica better get out of there fast before the police arrive. It looks like the ex-couple's criminal days are far from over.

Meanwhile, the synopsis (as per CarterMatt) reveals that the Fiona (Emmy Rossum) is ready to throw in the towel on her laundromat business. She just cannot handle the expenses that go with it. The repairs needed in the place cost a lot of money. Fiona is thinking of selling the laundromat but to whom? She will definitely have a tough time looking for a buyer at this rate.

With so many things in her mind, Fiona does not have the energy to deal with Lip (Jeremy Allen White), who is starting to go back to his old alcoholic self. Elsewhere, Ian (Cameron Monaghan) has a nasty suspicion that Mickey (Noel Fisher) is out to get him.

"Shameless" season 7 airs Sundays at 9 p.m. EST on Showtime.
