Here’s the Lowdown: Arterton stars as Kate Henderson, a senior MI6 officer leading the Russia Desk, whose seemingly ordinary life masks a high-stakes job. When she uncovers evidence suggesting a top UK politician might be a Russian agent, she faces a race against time amidst escalating danger. The impressive supporting cast includes Rafe Spall, Mark Stanley, Alex Kingston, Roger Allam, Amaka Okafor, and Khalid Abdalla.
