Watch the teaser trailer for the new HBO original limited series ‘The Sympathizer,’ starring Hoa Xuande, Sandra Oh, Robert Downey Jr., Fred Nguyen Khan, Toan Le, Ky Duyen, and more.

Based on Viet Thanh Nguyen’s Pulitzer Prize-winning novel of the same name, HBO describes ‘The Sympathizer’ as “an espionage thriller and cross-culture satire about the struggles of a half-French, half-Vietnamese communist spy during the final days of the Vietnam War and his resulting exile in the United States.” 

“Near the end of the Vietnam War, a plant who was embedded in the South Vietnam army flees to the United States and takes up residence in a refugee community, where he continues to secretly spy and report back to the Viet Cong,” the show summary reads.

‘The Sympathizer’ premieres April 14 on Max.
