Venom (1981)

The kidnap that became a murder, that became a siege, that became a death trap.

International terrorists attempt to kidnap a wealthy couple's child. Their plan comes unstuck when a deadly Black Mamba, sent by mistake instead of a harmless snake, escapes and the terrorists and several hostages are trapped in the boy's London home.
