In a attempt for a heist on this federal facility, the bad guys needed to take over the facility guarded by soldiers. Love the commitment from the main bad guy not to kill anyone (he even said so in the movie - this should happen more often, it's hotter haha). But the soldier guards were taken down one by one, this this high tech tranquilizer/electrifying bullet. Once they're incapacitate, they're ziptied, and locked in a caged area. What's missing is the gag, but I guess what's the point, they've taken the entire facility, and there's a hurricane going out outside, noone can hear them. Some hot taking down action, especially love the acting of being shot!
