September 2012, Ravensburg, Baden-Wurttemberg, Germany. A vocational school class from Ravensburg is having an informal getting to know each other at the start of the new school year with adventure-based learning. A lot of the kids have either a criminal or any other conspicuous past. Part of the afternoon programme is to build a chain of people over a slack-line, called Mohawk Walk, where they have to work together and take care of the weakest in order to complete the task.
