A trio of desperate suburban moms decide that being good never got them anywhere, and rob a supermarket in order to get a little cash to help them and their families out. Unfortunately, the supermarket is already the territory of a local gang, and the women soon find themselves in hot water.

The women struggle to come up with the money they owe the gang -- which, in this case, means robbing yet again. Meanwhile, Annie's fight for custody takes a major hit, Beth tries to navigate life as a single parent and Ruby's concerns for Sara's health escalate.

Beth comes home to a surprise guest and is forced to confess to Ruby and Annie that she asked Rio if they could continue working for him. Meanwhile, Beth throws Kenny an elaborate birthday party, which unexpectedly leads the women to offer Rio a business proposition. Ruby's employment at the diner is threatened by a disgruntled teenage customer and Greg gives Annie the benefit of the doubt when she comes up with a creative solution for dealing with some bullies from Sadie's school.

Business is booming and the women are living large, but a threat from one of their employees reminds them how violent Rio can be when pushed and threatens everything they've been working toward. Meanwhile, Beth and Ruby both enjoy the shifting dynamics in their respective marriages. Boomer carries out a malicious plot against Annie that puts her fight for custody in jeopardy.

Rio’s feeling the heat from the FBI investigation, so he abruptly shuts down operations, cutting off Beth, Ruby, and Annie's money supply. Their attempt to go back to being ordinary housewives is short-lived when Mary Pat puts the financial squeeze on them -- forcing the three women to commit another heist.

Rio asks the women to complete a seemingly simple job so he can get the operation up and running, but Beth, Ruby, and Annie fear there may be more to the task than meets the eye. As the ladies’ long-simmering tensions with the gang leader boil over, Ruby learns that Sara has risen to the top of the transplant list.

Fearing for their lives, the ladies scramble to try to take down Rio. A kidney becomes available for Sara but Ruby and Stan don’t have the money to pay for it. The three women hatch a plan that will solve both problems – one that involves returning to the scene of their first crime.

Beth must live with the fallout after her plan to get Rio arrested fails. Meanwhile, the women's crimes finally catch up with them when evidence surfaces that puts them on a collision course with Agent Turner.

Rio forces Beth, Annie, and Ruby to solve a problem with a possible witness, which challenges the women’s morality. Meanwhile, Annie is in an awkward position with Greg and Nancy.

Rio's new business opportunity for Beth leads to a fracture in her relationship with Annie.

Stan faces the consequences for his role in Ruby's criminal dealings; Dean gives Beth an ultimatum. Greg clashes with Annie's new boyfriend.

Beth makes a choice that surprises those around her just as an old foe from the past returns. Meanwhile, Annie finds a helpful outlet on her road to self-improvement.

Beth decides to find a solution to her Rio problem after he backs her into a corner; Ruby enlists Sara's reluctant help to replenish supplies after a key counterfeiting component dries up; Annie spirals after a vulnerable session.

The pressure is on after Lucy's body is discovered in a graveyard; Beth and Dean do everything they can to get Boland's Bubbles up and running but encounter red tape. Harry gets in trouble and his teacher encourages Ruby and Stan to get him tested.

A huge client approaches Dean to sell his merchandise at Boland's Bubbles, but Beth is hesitant. Stan and Ruby's guilt reaches a breaking point when Sara's donor family returns. Annie tries to prove to Ben that she can keep up with the rich parents at his school.

Ruby and Annie get frustrated with Beth. Things change when Rio asks Beth to recruit a new team member. Stan is wary of involving Beth in new business. Annie is convinced to pull Ben from private school.
