The movie 10x10 is a thriller that focuses on Lewis, a seemingly average man who has been harboring a deep-seated grudge against Cathy, a woman whose connection to him is only revealed later in the movie. Lewis is meticulous and precise in his planning, and when he finally kidnaps Cathy in broad daylight, he takes her to his remote home and locks her in a soundproof cell.
Cathy, understandably terrified and confused, has no idea why she has been kidnapped and what Lewis wants from her. Lewis is determined to extract a secret from her that he believes she has been hiding for years, but Cathy denies any knowledge of what he's talking about.
As the days pass, tensions rise between Lewis and Cathy, and Cathy becomes increasingly desperate to escape. Meanwhile, the police are investigating her disappearance, and her family and friends are frantically searching for her. But with no leads and no witnesses, they seem to be running out of time.
The movie is a tense and thrilling cat-and-mouse game between the two characters, with both Lewis and Cathy revealing unexpected layers of themselves as the plot twists and turns to its shocking conclusion.
