Beyond the Seventh Door (1987)
Plot: Wendy, a professional thief, and her ex-boyfriend Boris break into a sprawling, gothic castle owned by a wealthy and eccentric man who has recently passed away. They believe the house contains a hidden treasure, but they soon discover that the interior is a deadly, multi-layered trap. To reach the treasure, they must navigate seven sequential rooms, each containing a unique and lethal puzzle or "door" that requires them to risk their lives. As they progress, the mechanical traps become increasingly sadistic, testing their sanity and their relationship as they realize the house itself is designed to ensure no one leaves alive.
