Surviving the Deserted Island is a 30-episode rebirth revenge drama. Luna, a veteran wilderness survival expert, co-founded a tech company with her boyfriend David over six years. On the fifth day of an island retreat, David and his mistress—secretary Linda—conspire to push her into the sea, plotting to claim her life insurance and seize her shares. Drowning, Luna dies seeing the truth; but just before a tsunami engulfs the island, she is reborn, waking on the morning of the disaster. Armed with ten years of survival skills, she secretly stockpiles supplies in a mountain cave and refuses to board the boat. Enraged, David ties her to a tree, but geologist John rescues her. After the tsunami destroys the island, David twists the truth, expels her from the shelter, incites the employees to raid her camp, and tricks them into eating poisonous berries—poisoning everyone but himself. Luna defends her camp with a homemade bow and traps. When a wolf pack attacks, Linda finally breaks down and confesses all of David's crimes: the insurance fraud, the murder plot, the lies. Desperate, David sets the forest on fire and is subdued at the seaside. When rescue arrives, everyone testifies against him, and both David and Linda are arrested. Luna completes her revenge—and learns to trust and start anew.
