Home2Home tells the story of Dennis Kailing who travels 43,600 km (27,000 miles) through 41 countries on 6 continents to circumnavigate the planet in 761 days. He does it on a bicycle - on his first bike journey ever. With the question "What makes you happy", but without experience in bike traveling, the 24-year-old from Germany jumps into the deep end and simply sets off - always heading east.
