The first trailer of thriller "Imperium" has arrived. Daniel Radcliffe stars as a young and idealistic FBI agent named Nate Foster who infiltrates a group of white supremacists in order to foil a radical right-wing terrorist group's attempt to make a dirty bomb.

In the trailer, Foster is recruited by a senior agent named Angela Zampino (Toni Collette) and asked to go undercover as a neo-Nazi's follower. "I need an informant. Get in there and make a difference," she says. "I don't have the skills for this," he replies, "I can't even defend myself!" Foster is heard in voiceover, "Big things are coming," indicating the terrorists group already makes their move.

Several scenes show Foster willing to shave his head, get a tattoo on his body and spend all his time with the white supremacist group. The bright up-and-coming analyst must confront the challenge of sticking to a new identity while maintaining his real principles as he navigates the dangerous underworld of white supremacy.

Inspired by a true story of Michael German, a former agent who spent years inside the neo-Nazi movement, the film is directed by Daniel Ragussis. He and German co-wrote the script. "Imperium" also stars Tracy Letts, Nestor Carbonell, Burn Gorman, Set Numrich and Sam Trammell. The film hits U.S. theaters on August 19.
