Venom (1981)

In the heart of London's elite neighbourhood, an affluent couple's life is thrown into chaos as international terrorists cunningly plot a high-stakes abduction of their only child. However, their meticulously planned scheme unravels when a deadly Black Mamba snake, sent erroneously instead of a harmless species, breaks free, transforming their would-be sanctuary into a venomous death trap. The predators soon become the prey as the terrorists, along with a handful of unfortunate hostages, find themselves ensnared within the opulent confines of the boy's London abode, trapped not only by the relentless police siege outside but also by the lethal predator slithering unchecked within its walls. With the evening stretching into a nerve-wracking battle of survival, the house turns into a serpentine labyrinth of fear. The Black Mamba, silent and swift, begins a terrifying game of hide and seek, stalking and striking the occupants one by one. In this deadly intertwining of terror and venom, the hunters and the hunted are pushed to the brink, where survival is as unpredictable as the snake's next strike. Venom is a tense, thrilling ride that takes you from a high-stakes kidnapping plot to a heart-stopping battle with one of nature's deadliest assassins.
