His grandparents were overweight. His parents were overweight. And so is Uli von Unglesheim. You might even call him fat. That’s why he hasn’t left his small castle in 10 years, and the only people he’s had any contact with are his old butler Heinrich, Susanna, Heinrich’s pretty granddaughter and the old gardener Wilhelm.
Susanna and Uli have been friends ever since they were kids, but Uli is oblivious to the fact that her feelings for him go beyond friendship. He is convinced that nobody – especially no woman – would want anything to do with him.
But his reclusive existence is shattered when he is hit with the news that he’s used up his inheritance! Even worse, he still owes an enormous sum of money to his old nemesis Paul.
Just when it seems he’s about to lose his castle home forever, he receives a surprising offer for a business venture – from Japan!
Uli has no choice but to travel to Tokyo in order to convince the Japanese that he is the right man for the job.
In the wondrous and foreign metropolis, Uli encounters a whole new world with strange and fascinating ways… and he experiences something completely unexpected and new.
To his amazement, everyone is exceedingly nice to him. Nobody seems at all fazed by his massive proportions – quite the contrary. As he meets and immediately falls for the beautiful geisha Mayumi and as well discovers the fascinating world of Sumo, where wrestlers far heavier than himself are adored and praised as heroes, he begins to gain a confidence he has never known before.
Even though the unscrupulous Paul tries to foil his plans at every turn, Uli is no longer willing to be intimidated.
With newfound courage, he fights to get the job and save his castle… and return home, because he has come to realize just how much Susanna really means to him.
