The concluding chapter of the three-part film series which started with My Fault: London and has been following the forbidden romance between Noah and her stepbrother Nick. In Our Fault: London, Noah and Nick face events that will force them to make a final decision: are they meant to be together or should they part ways?

Marfil Cortés, a daughter of a wealthy Spanish businessman, is kidnapped and released, leading her father to hire Sebastian Moore as a bodyguard. Despite initial clashes, they form an irremediable attraction, navigating a world where no one is who they say they are.

Nick and Noah are both embarking on life-changing adventures that are threatening to pull them apart—Nick in business with his father and Noah starting a fresh chapter at Oxford University. Now living separate lives, and meeting new people, they find themselves entangled in temptations, rivalries, and betrayals and their bond is tested like never before. As secrets unravel and temptation rises, they must fight to hold onto each other—or risk losing everything.
