Bodyguard (Season 1)

Bodyguard (2018) is the BBC One political thriller you can watch online on iFILM. Police sergeant and Afghanistan veteran David Budd draws an assignment he can't stomach: guarding Home Secretary Julia Montague, whose hardline politics he quietly despises.

The opening episode hands you a hijacked train and a bomb Budd talks down with his bare hands, and the show never quite lets your shoulders drop after that. What follows is a closeness that shouldn't exist between protector and principal, explosions in the middle of London, and a creeping sense that the threat lives inside the system. Richard Madden plays Budd wound tight as a wire; Keeley Hawes makes Montague impossible to read. Six episodes, one season — worth streaming all the way through, since each ending leaves you dangling.

Writer Jed Mercurio, the mind behind Line of Duty, brings his signature trick: you trust no one until the last reveal. Madden took home a Golden Globe for the role. It's the rare case where "tense" isn't marketing but a literal description of your pulse. Stream Bodyguard (2018) online on iFILM.
