Imperium

Imperium (2016) is a crime drama you can watch online on iFILM, with Daniel Radcliffe playing FBI analyst Nate Foster — a soft-spoken idealist sent undercover into a white supremacist network suspected of planning a radiological attack.

The job means shaving his head, learning the rhetoric, showing up to rallies and convincing men who trust no one that he belongs there. Toni Collette plays his handler Angela Zamparo, the one voice on the outside keeping him tethered. Every day Nate stays under, the line between cover identity and actual self gets harder to trace.

Director Daniel Ragussis co-wrote the script with former FBI agent Michael German, whose real casework underpins the story. Radcliffe plays Nate without any of the toughness the role might invite — nervy, quiet, always a half-second from exposure. That restraint is what makes the film land. Watch Imperium online on iFILM.
