A tale told to Shane by his grandfather with is dying breath leads Street Smart to take on the most dangerous gangsters in the whole suburb. Their mission: to rob the safe of a school uniform factory serving as a front for a money laundering operation. Capitalising on Tia's gift for not being noticed, Joseph has her infiltrate his cousin's gang. Will Steve let her into the gang or his heart?

The gang steals shopping trolleys for the deposits, but when things don't go quite as planned, they have to return them before they're caught.

A real gangster comes to town and (mis)hears the gang's latest plans, and wants in. Vince has somehow evaded the law for years, but Joseph plans to bring him down.

Steve's new skeleton key has the potential to get the gang into any vending machine in the world — drink machines, snack machines, skill testers — it's a license to print coins! Using his new drone, Joseph learns of Steve's plan to clean out the mall's vending machines but the two wind up trapped in a Dumpster together. Meanwhile, Joseph and Steve's mothers arrange for the cousins to meet a girl.

Steve is re-elected president of Street Smart in accordance to the democratic rules outlined in group's constitution. Having campaigned on the promise to make Street Smart great again, Steve begins by converting the Pork Roll & Nail Bar into a pop up nightclub while Trans is away competing for her fifth consecutive title at the Banh Mi Masters Conference.

Steve holds a garage sale to fund Street Smart's next big job but after unwittingly selling off a valuable bowl, he must conduct a daring heist to recover the family heirloom. Meanwhile, Joseph becomes ASIO's newest agent.

Preying on the insecurities of vein, shallow people with too much money to spend, Steve's latest idea for Street Smart is to mix up a batch of his mother's secret herbal skin cream — they'll make a killing!

Steve tells the gang that the police station has a whole room full of confiscated items, so they decide to break in and steal them. Joseph discovers the plans and hopes to foil the attempt.
