10x10 (2018) is a tightly wound British-American psychological thriller that traps viewers in a claustrophobic game of cat and mouse. The film follows Lewis (Luke Evans), a seemingly ordinary man who meticulously kidnaps Cathy (Kelly Reilly), a local florist, imprisoning her in a 10x10 foot soundproofed room. His motive isn't ransom, but interrogation—he is determined to uncover a specific, traumatic secret from her past, suggesting their connection runs deeper than a random attack.

Director Suzi Ewing crafts palpable tension within the minimal confines of the single location. The narrative's power derives from the shifting dynamic between captor and captive, as layers of both characters are peeled back. Luke Evans delivers a performance of controlled intensity, while Kelly Reilly is compelling as a woman who must use her wits to survive, revealing unexpected resilience. The mystery of 'why' drives the plot forward, transforming a simple premise into an engaging puzzle.

While the film's limited setting and straightforward plot may not appeal to all, it succeeds as an efficient, suspense-driven thriller. The central performances and the gradual unraveling of the characters' shared history provide enough intrigue to maintain engagement for its brisk 88-minute runtime. For viewers who enjoy tense, dialogue-heavy thrillers that explore themes of guilt, trauma, and revenge within a confined space, 10x10 is a compelling watch that proves a simple concept can be effectively gripping.
