Jim's let his mind wander to other women during sex with his wife before. He's even strayed physically a few times. But he's never cheated on her with a prostitute...until today.
Bad move: This hooker is a time machine. No, really. Sleeping with her transports Jim back to whatever intimate moment he's thinking of when their act of adultery begins. At first the literal flashbacks are intoxicating, but when they cause him to destroy his present, they become the only means of salvaging what's left of his life...and finally doing right by his wife.
