Linda has a busy day of job hunting lined up, and Hattie gives her daughter some advice on how to make a good impression for her interview.
Later, Vivian, the woman who owns a competing restaurant and the building that Floyd works for, visits the Love Train Diner and asks for Floyd's assistance. He leaves, and Hattie lets Linda, who has returned from her interview, run the diner while Hattie runs to the bank. Unfortunately, though, the health inspector pays a surprise visit to the diner, and because of Linda's negligence, he shuts down the restaurant.
Later, the health inspector returns and flirts with Linda, and with his help, Floyd and Linda are able to get the Love Train Diner back up to code and open the doors once again.
Linda shows up at Floyd's tiny studio apartment at 3 a.m. looking for a place to stay. She explains that Lionel, whom she is currently divorcing, has canceled her credit cards and that her mother, Hattie, has refused to let her in.
Floyd attempts to play peacemaker by petitioning a headstrong Hattie to help her needy daughter; however, Linda is given a dose of Hattie's tough love when Hattie physically attacks her in an effort to get her to "fight" for herself. With her blinders removed, Linda decides to stand on her own two feet.
Afterward, Hattie lets Linda move back home again—but only for three months.
As Linda grieves the loss of her marriage, Hattie encourages her, in typical Hattie fashion, to get a job, take care of herself and move on from her philandering husband.
Meanwhile, Danny accuses Sam of partying too much, and Sam asks Danny to do something about his clingy mother always being at their apartment. While Danny is submitting good work at Beagal and Steve, he ignores his mother, which leads to an unpleasant confrontation.
Ultimately, mother and son resolve their issue, and Linda agrees to give Danny some space.
Sam has had enough of Linda's visits to the bachelor pad, the last straw coming when he walks into the kitchen—completely naked—only to find her there. After Sam discovers that Danny has given Linda a key to the apartment, he confronts Danny about Linda wearing out her welcome. Sam demands that Danny get the key back. Danny is not convinced until Linda's visits cause him to miss a deadline at work. The quest to get the key back begins.
Danny begs Hattie to tell Linda, but Hattie tells Danny to get some backbone. After much coaxing, Danny passively tells Linda to give up the key.
A week after learning about Lionel's affair with Crystal, Linda is depressed and sleeping on Hattie Mae's sofa. Broke and feeling like she has no marketable skills, Linda considers working things out with Lionel. Hattie is disgusted by her daughter's behavior and exercises tough love by putting Linda out.
At the same time, Danny finds his own independence when he leaves the nest and agrees to move into the extra room at Sam's bachelor pad.
Grandma Hattie is frustrated that her grandson, Danny, still hasn't found a job since his graduation from college. Hattie motivates him to get out and go look for a job. Later, Danny's friends get him an interview at their place of employment, and he gets hired.
Meanwhile, Floyd stumbles upon Linda's philandering husband, Lionel, cheating with another woman. Floyd decides not to divulge this recent discovery to Linda but tells Hattie instead. Hattie purposely exposes Lionel's recent indiscretions in front of everyone. Because of this, Linda decides to move back in with Hattie.
