Shane is trying to take over control of the city, putting any troublemakers into boxes that he has all over the city. The only problem is that once you start going after them, it'll only be a couple of minutes before Shane finds out. Head to the first shipping container and quickly take out both of the thugs there.
Open the container to find it empty and now begins the annoying part of the mission. Jenny will pinpoint where the next shipping container is located, but you only have so long to get there, with the timer displayed on your screen. You can use your Light Speed ability to run through the Neon Clouds, which will extend the timer a little bit each one you go through.
Once you get to the container, the timer will stop, so quickly take out Shane's men there (there's four), then open the container and head to the next one. On your way there, you'll notice that the police, both on foot and in cars, will attempt to stop you. Although they can't really do that, they'll lay smoke traps throughout your run, which WILL stop you in your tracks.
At the third container, you'll find a total of five thugs, so defeat them and head to the fourth, and last, container (yes, the police will do the same thing while on the way). Take out Shane's thugs, open the container, and then the crap hits the fan. Follow the signal to her location, only to find something tragic.
