A case of an old man's lost love returning from out of the blue takes on a few unexpected twists when Magnum investigates. Meanwhile, Rick and TC reach out to a disabled and depressed fellow veteran to try and help him back on his feet.
Magnum is being held hostage by a man named Viktor. They bring in two men, it is TC and Rick. Magnum grabs the gun from Viktor and takes them all out. Juliet laughs at this story out loud while reading an excerpt in the middle of a tour with children. They are there after reading Robin’s famous adventure books, the White Knight. They run into Magnum, who they love. Juliet is irritated even more.
TC and Rick see a veteran outside a neighborhood convenient store and decide to buy him a beer and hangout. Meanwhile, Magnum heads to meet a new client named Henry. He is very rich and old and hasn’t left his estate in years. His butler tells Magnum his memory has been going for years. Today is a good day. He wants Magnum to find his first love, named Elizabeth. She recently sent him an email, he tells Magnum. Magnum wants to know why he doesn’t just respond. Henry tells him he isn’t sure it is her because she has been dead for 30 years. The email asks for financial assistance.
TC and Rick ask the veteran to tag along for some surfing. He is in a wheelchair, telling them his legs don’t work too well. They tell him some of their disabled veteran friends surf.
Magnum gets Juliet to help him on his case. She finds out that the email was sent from a library IP address. At the library, they manage to get into the system and the cameras. It is Liz. Magnum and Juliet head to see Henry. They send Liz an email to see what information they can get. Henry suddenly has an episode. He hits himself and forgets what it is going on. Juliet helps him. It makes Magnum smile.
TC and Rick get their new friend on a board. They all have fun, laughing and taking in the waves. Their friend starts to feel better.
Juliet and magnum get an email from Liz with only an image, no texts. Kumu tells them that the photo is of a local park. They head there.
In the park, Juliet tells Magnum her mother had the same episode as Henry. That is why she knew what to do. They come up on a freshly dug grave with blood on the ground.
Magnum brings the blood to a local lab. He bribes the doctor with dinner out for 2. Meanwhile, TC and Rick watch their new friend purposely fall off his board and sink to the bottom of the ocean. They grab him. He gets mad at them for saving him. He cries because he missed an IED in some road kill because he was tired and rushing. He got his friends killed and now he is in the chair. They tell him they struggle too and they want to have his back. They can help.
Juliet calls Magnum. Liz had medical debt after giving up a baby for adoption. Magnum is told the grave blood is from swine. He heads back to the park and finds a nearby cabin with swine hanging. In the cabin, he finds letters involving Liz and human skulls. A man named Earl with a bow comes in. His girlfriend shows up too. He tells her to get rid of the car while he walks Magnum into the woods. When the car alarm goes off, Magnum runs for it. Earl starts shooting bows. Magnum hides and jumps out hitting him with a piece of wood.
Juliet arrives after the police show up. She looks over the letters in the cabin. They are sure now that Henry’s butler, whose sister married Henry, was the one behind all of this. He killed Liz and then got rid of her when she became pregnant. He buried her out in the woods. Earl came across all of this and decided to try and take advantage.
Magnum confronts the butler who admits it all. The police take him away. They tell Henry everything and that they found his daughter with Liz. Her name is Sara.
TC and Rick ask their friend to help them out with TC’s chopper business. He’s happy to do it. Meanwhile, Magnum and Juliet unite Henry and Sara.

- In Hawaii Five-0 season 7 episode 3, which is set in the same universe as this show, Kono Kalakaua reconnects with an old surfing buddy who has lost both legs while serving in the military. They go surfing together, which is very similar to to Rick and TC taking Shammy surfing in this episode.
