Story: When crates arrive at Chicago’s Field Museum containing mysterious South American artifacts and strange leaves, a horrific monster is unleashed. Detective Vincent D’Agosta teams up with evolutionary biologist Margo Green to track it down before it kills again. The beast, revealed to be the Kothoga—a mutated chimera combining insect, reptile, and human DNA—rampages through the museum during a high‑profile gala, decapitating victims and extracting their pituitary glands. As chaos erupts, Margo and D’Agosta must force open sealed passageways, confront hidden corridors under the museum, and ultimately stop the creature using science and strategy. The film culminates in a tense underground showdown and fiery confrontation in the museum labs.
