Cathy doesn't want to be the one who is always responsible and in control, especially now that she has been diagnosed with a terminal case of melanoma. That's why she kicked Paul out of the house as she literally wants to be the one in their twosome who is seen as the person who freely spills wine on the sofa without caring, instead of that person always being Paul. That's why she's decided that she wants a pool built in their postage stamp sized yard, so that she can teach Adam how to do the banana split dive like she did when she was his age. That's why she feels that she can give Adam a taste of his own medicine by treating him as thoughtlessly as he seems to treat her, all in an effort to make a point. That's why she feels that she can be blunt instead of being politically correct to her student Andrea about the combination of her wisecracking and her weight. That's why she decides that she doesn't need to be cordial anymore to their crotchety neighbor, whose name she doesn't even know after living next to her for five years. And that's why she tries to reach out to Sean despite Sean abhorring everything about what he sees as Cathy's chosen bourgeois lifestyle. Regardless of these changes, Cathy isn't yet ready to tell anyone, let alone her family - Paul, Adam or Sean - that she is dying.

Cathy learns from Dr. Mauer that she probably has at least a year to live if not longer, which gives her some perspective of how much time she has left to do the things she wants. Chief among these is spending time with Adam. So instead of allowing him to go away to soccer camp for six weeks over the summer, she decides unilaterally for him to stay home over the summer so that they can spend time together. Cathy's actions seem crazy to Adam and Paul, both who still don't know about her medical diagnosis. Regardless, Cathy goes to extreme lengths to get what she wants. Dr. Mauer's time estimate also makes Cathy examine her body image, which she is doing truly for the first time in her life. What she sees surprises her. Meanwhile, Paul still isn't sure why Cathy won't let him come home and thus suggests they attend marriage counseling. Cathy treats the sessions with the knowledge of what she knows is the problem in relation to her health situation without divulging anything about the melanoma.

Since she knows she won't reach retirement age, Cathy decides to withdraw all the funds from her retirement plan and do whatever she wants to with the money without a care. Among other things, she indulges on material goods such as an expensive bottle of champagne, which she shares with her new confidante, Marlene. But her biggest purchase is a red convertible sports car, which she can't drive since she doesn't know how to drive a stick shift. Regardless, she decides to spend the day with her new toy and Dr. Todd house hunting while pretending to be his older girlfriend. In the process, she liberates a lobster. That time with Dr. Todd shows her where her true future lies. Meanwhile, Paul, looking for something meaningful to do in his life while he's not at home, decides to head back to his school days and play rugby again. Sean, who has a toothache, refuses Cathy's offer of paying for a dental visit. Sean goes to extreme measures to deal with the tooth. And Marlene takes on the role of pretend grandmother to Adam, whether he likes it or not.

During the course of their continuing sexual relationship where they do it anywhere they can on unofficial breaks during the school day, Lenny notices a lump on Cathy's lower back side. Dr. Todd's diagnosis is that the cancer is showing itself, but that it does not necessarily mean that the cancer is getting worse. As it is purely a cosmetic issue, Cathy can choose to leave the lump or have it removed. She chooses the latter, and asks the only person who knows, Marlene, to pick her up after the surgery. The lump makes Marlene try to convince Cathy to tell her family about the cancer. It makes Cathy reevaluate her sexual relationship with Lenny and think about bringing her family back together, which includes not only Paul but also Sean. She figures that entering the family into a charity bathtub race, a race they used to always participate in and enjoy, but which Cathy stopped doing because of all the work involved on her end, is a good start. Some news from Paul, and Andrea finding out about Cathy and Lenny could bring Cathy's current plans crashing down around her.

Paul discovers his wife's affair and demands a divorce.

Now that Paul knows about Cathy's melanoma, he wants to help her in any way he can, including investigating alternate treatments. He is also still trying to get over the fact that he lost three months in trying to help her, three months in her probably shortened life. Cathy tries to explain to him why she didn't didn't tell him sooner. Paul, in dealing with the spouse of someone who died of cancer, begins to move closer to Cathy's way of thinking. Meanwhile, Rebecca tells Sean that she is moving to Minneapolis, but doesn't quite get the reaction she wanted. In a girls' bonding session, Marlene, Cathy and Rebecca go out for lunch to an unusual locale, an incident at which makes Cathy believe that Paul's thoughts about dealing with her illness aren't completely wrong. And Cathy learns about Marlene's Alzheimer's.

In an effort to be supportive of Cathy's decision and to find out more about it, Dr. Todd accompanies Cathy to Canada for her bee sting therapy. As open as he tries to be, Dr. Todd just can't get around how quackish the whole therapy seems. After the treatment, Cathy too believes that the "Bee Man" is a lunatic, but is glad she made the decision to take a chance. As their trip progresses, many revelations about Dr. Todd's professional and personal life become known to Cathy, which explains why he seems so protective about Cathy and why he wanted to come on this trip. Before she left Minneapolis, Cathy found out that Adam is seeing a girl named Mia, who, if she is indeed his girlfriend, would be his first. Cathy takes an extreme but nonetheless effective measure to ensure that things go well for Mia and Adam's possible relationship, despite the less than helpful advice he receives from his Uncle Sean. And an incident between Marlene, Adam, and Paul makes Marlene take decisive action.

Following Marlene's death, Cathy learns Marlene left her house. At first she's willing to let her daughters have it till she learns what their plans are. Dr. Miller wants her to try a different treatment which is risky. And she learns that Sean and Rebecca are expecting a baby.

Cathy seeks a second opinion, causing a strain on her relationship with Dr. Todd; Sean learns about his sister's cancer while adjusting to life with a pregnant Rebecca; Adam sees a therapist against his will.

Cathy believes the two best Christmas presents she received this year are Sean returning home after missing for three weeks while he went to find himself following Rebecca's departure, and watching Lee die peacefully in front of her, which has now made her not afraid of death. Taking a play from Lee, Cathy decides to finish what Lee didn't and couldn't: run the Minneapolis New Year's Eve Marathon, despite she not having trained for it at all. Her new mantra is to use her body while she still can. But the race entries have closed already which means that she has to find a creative way to enter the race. Adam receives an offer of reconciliation of sorts from Mia, which may interfere with something he feels is more important in his life at this time. And Cathy finds out about Paul and the electronics store parting company and the reason why. As this affects their health insurance, Paul goes on his own mission to ensure they get from the insurance company what they deserve.
