Caged Angels. Mind over murder! Super-villains drafted into serving as federal marshals, the Thunderbolts specialize in hunting down unlicensed super heroes ? but they may be doing their jobs a bit too well. The prisons are full, so Thunderbolts Mountain is serving as a temporary jail while they process all their latest prisoners ? some of whom happen to be ruthless psychics bent on destroying the team from within. And since the Thunderbolts include horrific head-cases like Venom, Swordsman, Moonstone and the Green Goblin, a little mental manipulation can be a very dangerous thing!
