Barristers and former lovers Eric Bana and Rebecca Hall fall foul of shadowy government agents in this uneven but gripping conspiracy thriller

Barristers and former lovers Eric Bana and Rebecca Hall fall foul of shadowy government agents in this uneven but gripping conspiracy thriller.

Bana and Hall are called upon to defend a Turkish immigrant accused of masterminding a terror attack on London’s Borough Market. The ensuing plot, cooked up by screenwriter Steven Knight, sometimes gets bogged down in legal intricacies – with much effort expended on explaining why the defendant has to be tried in a closed hearing away from prying public eyes.

However, when the intrigue gets going, it has a clammy suspense and there are striking supporting turns from the likes of Riz Ahmed as a slick MI5 agent and Jim Broadbent as the Attorney General, who veers scarily from slippery bonhomie to silky menace.
