About the series

After a botched assignment, MI5 agent River Cartwright is sent to Slough House, a department where disgraced agents are sidelined after making serious mistakes. Under the supervision of the abrasive Jackson Lamb, the team is given routine administrative work until a dangerous case pulls them into an operation involving a kidnapping, a terrorist threat, and secrets buried within British intelligence. As the investigation unfolds, the agents discover that the threat reaches deeper into MI5 than they expected, forcing them to act against orders to uncover the truth.
