Harley is a resident at the Glorious Pines retirement community. Just when Shawn and Gus think that they've solved the Oswald Chester case, Harley falls ill as well and needs to be rescued after fainting into the pool. Shawn and Henry have both noticed that he and third victim Sam are wearing the same bracelet they had earlier seen in Oswald's room.
At the station Gus shares his theory that they could be dealing with an "angel of death" scenario, but Lassiter and Juliet believe it's more likely that all three residents simply fainted as a result of the current heat wave and Walker and Ramachandran had earlier told Shawn that it's not uncommon for the elderly to accidentally give themselves an overdose of medication. Jervis Kent, a security guard at the home, tries to get the police to finally start a proper investigation, but he's again not taken seriously. Juliet says that none of the doctors treating the patients suspect foul play, but Shawn mentions the bracelet connection and convinces Karen to let them keep investigating.
Back at Glorious Pines, Jervis informs Shawn and Gus that Chelsea makes the bracelets in craft class and "doesn't just give 'em to anybody." Our duo then see her tangoing with Henry, and Shawn cuts in twice as he and Henry alternate dancing with her while asking her about the case. She tells them that Harley is an ex-boyfriend whom she met at the "heart-smart high blood pressure seminar" that she hosts.
They think the case through one more time, and when Henry suddenly remembers that someone had recently stolen blood pressure medication out of the on-site pharmacy their suspicion of foul play only grows. Shawn and Gus sneak into chief administrator Pamela's office in hopes of finding a list of residents on this medication so that they can identify potential targets, but instead they discover information that solves the case on the spot: a waiting list to get into the home with Rhonda Cloverfield, mother of the Meredith Cloverfield in charge of room service, in seventh place. Meredith wanted to bump her mother up the list to get her out of the terrible Sunshine Meadows home as soon as possible and knew that Glorious Pines does not provide full-time medical care, so she stole the medication and slipped it into the food of the three victims to ensure they would overdose and get kicked out of the home after forever losing their good health. She knew they were already on the medication thanks to the friendship bracelets the uninvolved Chelsea would give those who attended her seminar. Meredith is arrested and later makes a full confession.
