A group of women preparing for a party on a luxury cruiser are suddenly hijacked by a man seeking to escape to a private paradise. After the boat crashes on a remote desert island, the survivors must navigate the dangerous terrain and hide from their captor. With one of their friends captured and the radio destroyed, the women are left stranded and hunted in a desperate fight for survival.
After Natsuno and Hitomi narrowly escape their tormentors and reunite with the other survivors, the group struggles to build trust and overcome their guilt. However, their fragile peace is shattered when Yuka is captured and coerced into spying for the antagonists. Now facing a hidden threat within their own circle, the survivors must unite and devise a desperate plan to escape the island.
Tensions peak among the survivors as suspicion and blame tear the group apart, with Natsuno blaming Toko for their predicament. Their fragile sanctuary is destroyed when Flora is captured and assaulted by Kaneda's group, sparking accusations of betrayal within the camp. While Mr. Aoki attempts to comfort a distraught Natsuno, Ayaka's desperate desire to share the group's trauma leads to a tragic outcome when she is captured by the predators, leaving the remaining survivors in despair.
Toko and Yuka attempt to rescue Ayaka, only to discover that Yuka has betrayed them to work with the sadistic Kaneda and Aoki. After enduring further trauma and navigating a web of betrayals, the women coordinate a daring counter-attack. Through Natsuno's deception and Flora's timely intervention, they finally overpower Kaneda, ending the nightmare and securing the rescue of all the missing women.
