Imperium

Nate Foster is an idealistic young FBI analyst who goes undercover to bring down a dangerous white supremacist cell. He adopts a new identity and sinks into the movement, moving through secretive rallies, code words and private chats. As the operation deepens, he must balance the demands of the assignment with his own moral code, knowing a single misstep could reveal his cover or derail the investigation. The story, rooted in real life events, traces his double life and the constant tension of staying in character while wrestling with his beliefs, fear and the corrosive allure of hate. It’s a stark look at how extremism operates from the inside. The atmosphere stays taut as the stakes rise.

Directed by Daniel Ragussis, Imperium translates Michael German's real life undercover work into a lean, tense drama with a focus on character and procedure rather than loud rhetoric.

Critics note the film's restrained tone and its emphasis on identity, trust, and the moral cost of undercover work. Radcliffe gives a controlled performance as a conflicted agent navigating loyalty to duty against personal convictions, while the screenplay keeps political extremism at arm's length from sensationalism.

Imperium slots into a niche of procedural dramas that examine how anti hate movements operate from the inside and how law enforcement balances risk with ethics. The film prompts viewers to consider radicalization, representation in media, and the real world costs of undercover investigations.
