“Legends” stars Sean Bean (“Game of Thrones”) as an undercover FBI agent with the ability to become just about anyone. But as this trailer for the TNT thriller makes clear, the hero may not really know who he is.

Bean plays Martin Odum, the star of the FBI’s Deep Cover Operations (DCO) division. While he must continue to work undercover — as everyone from a Chicago cop to a Serbian extremist — Martin is also desperate to discover the mysteries of his own past.

“Legends” premieres Wednesday, Aug. 13 at 9 p.m. ET/PT on TNT and co-stars Ali Larter, Morris Chestnut, Tina Majorino, Steve Harris, Amber Valletta and Mason Cook.
