On her final day as a medical student, Masters needs a tenth lumbar puncture to complete her medical log. She is also shocked to learn that House has created an opening in his diagnostics team so that she can join as an intern. Masters is introduced to Thirteen, and as the rest of the team arrive, House claims that the missing Doctor has been in drug rehab, keeping her prison shame a secret. The team start work on a new case: Kendall Pierson, a teenage girl who wants to be the youngest person to sail the world. After Kendall collapses during a practice run, the team perform tests to check for an an adrenal insufficiency.
After several failed attempts to get her final lumbar puncture, Masters decides to accept House's internship, but he forges the final LP on her medical log and tells her that she can only join his team if she hands in the forged document. However, Thirteen later offers Masters the opportunity to perform the final LP on her. Meanwhile, Kendall falls into unconsciousness and suffers from poor blood flow to one of her arms. Further tests appear to reveal that her pineal gland has become calcified and the team start the patient on hormone therapy.
Masters tells House that she has handed in her log, but he is able to detect from Thirteen's "stiff gait and small pupils" that Masters remained honest and performed the final lumbar puncture. Masters insists that she can do her job without cheating or compromise, but House angrily withdraws the internship.
Masters departs House's team and starts a surgical internship. On her first day, her advice proves vital in saving a patient's life, which impresses the head surgeon. He invites Masters to scrub in on his next procedure, but she is distracted when she learns that Kendall's previous treatment failed and that she is still a patient. Masters makes an excuse and leaves the surgery to attend Kendall's operation. Impressed by her subterfuge, House welcomes her back to the team, but she insists that she is only staying for this one case.
Staying late at the hospital, Masters stumbles upon House and Wilson's latest antics - a bet to see who can keep a chicken in the hospital for longest without being detected by security. The chickens give her an idea and she decides to test Kendall for salmonella enteritidis, which manifests as an aching in the bones. As Chase and Masters scan Kendall's bones, he advises her to return to surgery. He warns that his own time with House has changed him, and not necessarily for the better. The pair do not find an infection in Kendall's bones, but cancer.
Masters tells Kendall that her arm needs to be amputated to save her life, but the teenager is desperate to delay her treatment and sail around the world. Kendall's mother bows to her demands, as does her father, albeit reluctantly. When Masters confronts House with the issue, he tells her that she must break the rules to save Kendall's life. Masters tries one final time to convince Kendall to have the surgery, and when she refuses, Masters gives her a special "medicine".
Kendall's heart begins to slow and she is rushed into surgery, with her parents being forced to sign a consent form to allow the amputation. House's team are shocked when Masters reveals that she caused the heart symptoms, but with the parents' consent, they amputate the arm. Kendall is devastated when she wakes, but her mother thanks Masters for all she has done.
The next day, Masters admits to House that she manipulated, lied, forged and stole to save Kendall's life, and that she now feels terrible. She tells House that she has to leave, as she cannot play by his rules. He warns Masters that "Nothing will ever be simple again" but she replies, "I'm fine with that" and proudly leaves the hospital.
