“The second season begins with Scott on a standard security mission in Kenya and Section 20 facing new pressures from command. Now out of the unit, Stonebridge is training recruits at a military base—” Wait, this guy is training troops?

When Scott’s mission takes an unexpected dangerous turn, Section 20 must find an immediate creative solution.” Strike Back strikes back tonight at 10pm on Cinemax.
