I am not her!

You have been kidnapped by insane man. His wife died in accident but apparently you look exactly like her. He believes she actually survived and now doesn't want to let you go. Alone with him, in a house far away from anything else, house where all doors and windows are locked shut with padlocks and chains... Can you survive? Can you actually escape? Can you seek help? You have to act smart, you have to turn on your survival instincts. You need to get out at all costs.
