Snake King Symbiosis

Three years ago, an excavator operator saved a giant snake guarding its young, but her foreman slashed its tail. Now her company bus has broken down in a rainforest teeming with mutated beasts. Her husband abandons her for his secretary, and the wounded snake returns to save her. At an abandoned ranger station, survivors turn on each other over supplies. She finds explosives that could trap a prehistoric crocodile in a narrow pass—but can she set them before someone stops her?
