Swedish cartoonist/rapper Simon Gardenfors left his home to spend four months on the road. His rules were simple: During the 120 days he wasn't allowed to return to his home, or to spend more than two nights at the same place. Otherwise, anything could happen - and it did. The result was an epic adventure across Sweden as Simon slept on strangers' couches, visited an ostrich farm, ate a psychedelic cactus, practiced free love, received death threats, was beaten up by teenagers, got adopted by a motorcycle gang, drank obscene amounts of alcohol, and sacrificed his underpants to the Nordic god Brage.
