In order to find peace, Tom (Lewis Fiander) and his wife Evelyn (Prunella Ransome) come to the remote Almansola Island, where the warm weather and beautiful scenery make Tom relaxed and happy, but the carefully impressed Evelyn found the weirdness. It turned out that this was an island with only children but no adults. Evelyn was very upset about the discovery, but they did not leave, and the gates of hell opened. Soon, the children on the island revealed their true faces-cruelty, violence and dehumanization. There were no adults on the island because they all died under the butcher's knives of the children. In the face of two uninvited guests, Tom and Evelyn, the children attacked. In the pursuit, Tom, as a biologist, gradually discovered that a strange virus was the root cause of these children's madness.
