It all began with a letter and the right kind of wind.

William Trümper leaves all he is and all he once knew behind, every part of his former self poured into the letters written on a blank piece of paper. Emerging as Bill Jost, he starts his new life with a clean sleeve and empty pages to be filled.

Tom Kaulitz refuses to let go of the past, but as a certain letter finds him, he finds the strength and inspiration to move one, to start anew.

Thrown together by a strong summer wind, Bill and Tom find themselves in an instant love and hate relationship. They don't seem to mix well, but fate seems to have plans for them, forcing them together against their will.

Why is it that Tom always understand Bill so well, though they've never met before? And can Bill finally step up to the task of being his true self, the self he left behind so long ago?
