Sean, JD and Kekoa have arrived on the Big Island to help with the extra work caused by the Ironman Triathlon. They are met at the airport by Russ, a native Hawaiian with a good sense of island lore and humor. Unknown th them, also on the Big Island is Jessie, JD's ex-girlfriend. Determined to win the Triathlon this time, Jessie has brought her newborn son, Luke with her. As she trains, she hears a woman, Sarah, screaming because her husband, John, a body boarder has disappeared. Jessie immediatwly springs into action and with the help of Kekoa, who is naturally surprised to see her, helps rescue John and bring him to shore. Unfortunaltely, it looks as if he broke his neck and might be paralyzed for good. Over the next few days, this diagnosis is confirmed and john will probably remain a quadriplegic for the rest of his life. Rather than face that fate, John refuses to have a life saving surgery done. Kekoa and Jessie are at a loss at how they can convince him to go on. This takes on particular significance because Sarah is pregnant and needs a father for her baby.

Jessie and JD have an awkward reunion-made moreso by the presence of luke. Nevertheless, JD, with the blessing Kekoa, who remains suspicious that JD has never gotten over Jessie, agrees to help Jessie train for the Ironman. Jessie is evasive concerning JD's questions regarding Luke's father. Finally, Jessie confesses. She told him that Luke was JD's son. Now, JD is in a worse quandary than ever. He wants to do the right thing, and this could mean returning to the states with Jessie. Kekoa is beside herself and JD isn't sure what he should do.

Meanwhile, Sean has decided to hike in one of the craters. He is warned by Russ that if he meets a hitchhiker along the way, he had better give the hitchhiker a ride because it might be the goddess of Pele and if he doesn't give her a ride, trouble will result. Sean does not believehim, but sure enough, on his way up the mountain, he runs into a woman hitch-hiking. Because he really wants to do the hike, Sean passes her by. Quickly, and per Russ' warning, Sean begins to experience trouble. His tire blows and his cell phone won't work. Later, as he is hiking, he hears a woman calling out for help. It is the same hitchhiker he passed earlier. She has fallen into a crevice. Sean saves her and she convinces him to bring her back to her house. They wind up spending some romantic time together. In the morning, she pleads that the foot is hurt. Sean, determined to continue on his way, refuses to listen at first, but ultimately is convinces to bring her down the hill. She brings him to a remote area where she claims to live. He hoped to see her again, but she says that will be impossible-there are other issues. Sean doesn't know how to get back. She tells him to just follow the line of the cliff. When he turns around, she had disappeared. As he walks along the cliff, he hears screaming. Jessie despondent over everything that has happened, had gone for a swim and gotten into trouble. Sean calls for backup and dives into the water to rescue her. She is pulled to shore.

Jessie confesses that Luke is not JD's son. She feels bad about lying to JD but confesses to Kekoa that she did not know what else to do. But, she has accepted the fact that JD and Kekoa are now and item and she will have to accept the fact that she is a part of his past and not his future. Kekoa, for her part, is glad to see the "old Jessie" has returned, and understands how stress can cause strange behaviors.

Jessie runs the race and finds JD, Kekoa, Sean and Russ waiting for her at the finishing line. Then, she and Kekoa go to visit Sarah and John at the hospital. She shows John her baby. He begins to understand how important his presence is.

At the airport, Sean hears a familiar voice. It is the woman he met on the mountain. She is a tour guide and is talking to a passenger. She and Sean share a whimsical, knowing smile.  My Score: 2 Rescue Cans
