Armed and dangerous, the Sweeney Flying Squad are London's elite crime fighting . Led by legendary Detective Jack Regan (Ray Winstone), they are not afraid to use old school, bare-knuckle tactics to bring down the modern underworld. Now, with a master criminal on the loose and a major bank heist in progress, Regan will do whatever it takes to get the job done, even if that means defying the orders of his boss (Damian Lewis) and taking the law into his own hands.
