In a post-war London, two sisters—one charismatic but impulsive, and the other more reserved and mysterious—lead seemingly normal lives. However, their world takes an unexpected turn when they find themselves caught in a complicated web of espionage. One night, a tragic and violent event shakes their existence, while the echo of their secrets threatens to unleash chaos.
With a cast of intricate characters surrounding them, the sisters are forced to grapple with their own morality as they get drawn into a network of political intrigue. Their relationship will be tested, revealing dark family secrets and hidden motivations. Their dreams of a quiet life turn into nightmares when they discover that not everyone is who they seem, and trust becomes one of the scarcest resources.
As they try to evade the forces pursuing them and unravel the mystery that envelops them, time runs out, and their decisions become increasingly critical. What began as a simple desire to survive transforms into a struggle for power, loyalty, and truth. Tension mounts, and each choice could be their last. In a game of cat and mouse, the sisters will learn that in life, just like in espionage, secrets can be deadly.
