This is the end scene, where a man (hero) chases a woman (villain). She manages to run into a dark room. When the man switches on the light, he sees her above him, on a higher platform, holding a rope, which is tied to a huge upstanding (white?) board with (rubber?) spikes. She laughs as she releases the board, which then falls on top of the man. Triumphantly the woman stands on the board with spikes, pinning the guy down and laughing at his predicament. It ends with police coming in and rescuing the man, the woman being arrested and led away. (I think she wore leopard skin trousers, though not sure. And it seemed British, like a Bond movie).
