Through a set of unusual circumstances, the Malloy family assumes the identities of a wealthy family, the Riches, only to find that a glamorous life entails more than they expected.

Wayne has to find a way to pay for the family's new lifestyle. Dale is still after the Malloys.

Wayne begins work at his new job at the law firm, where his first assignment is to fire the current head of the department. Meanwhile, Dahlia insists on registering the kids at a rich private school despite the fact that there are currently no openings. Finally, Dale uses his influence over Tammy, Cael's girlfriend, to track down the Malloys.

The real Doug Rich's ex-wife jeopardizes the Malloys' cover when she comes after "Doug" for missed alimony payments. Meanwhile, Di Di falls for a buffer, and Cael finds a way to capitalize on his unusual skills at school. Also, Dahlia's pill addiction continues to worsen and now threatens to tear the family apart.

Wayne must deal with legal arcana in an eminent-domain case and Dahlia gets a job for which she is equally qualified: a dental hygienist. Ginny catches up to the Malloys, which means Dale is probably not far behind.

Stunned by the news of Earl's death, a grieving Dahlia and her family head back to camp, where Dale looks to settle old scores with Wayne, while Ginny schemes to tie the knot between Di Di and Ken.

When Hugh suspects that Wayne and Dahlia stole money from the office bank, the Malloys must resort to doing what they do best: the con.

The family finds itself in awkward situations when Wayne is offered a partnership at Panco only if he throws a dinner party that meets Hugh's approval. Meanwhile, a former cellmate of Dahlia's on the search for a job wants to be the family's maid.

Wayne suspects that Dahlia still has a drug addiction and takes meth himself as a way of showing her how much the fact that she is on drugs hurts. Meanwhile, when things at Panco go crazy, it is up to Dahlia to keep everything and everyone together. Finally, Dale shows up at Edenfalls and befriends the family's neighbor, Hartley.

When Hugh goes missing, it is up to Wayne to take over at Panco and discover what it's really like to be the boss. Meanwhile, Dahlia tries to bond with Di Di, only to discover that their relationship has only taken more steps in the wrong direction. Finally, Dale confesses his intentions to Hartley.

The Malloys must hide their true secret extra carefully when Doug's friend Pete stops by for a visit, Hugh returns with a new wife from Las Vegas, and Hartley warms up to Dale and shows him how to blend in.

The Malloys find themselves in difficult situations as more visitors continue to arrive, neighbors pry and Dale aims for a piece of the action. The family finds itself making some difficult decisions.
