Four overweight friends from the Israeli city of Ramle are fed up with dieting and the dieting club they belong to.
When Herzl (155 kilos) loses his job as a cook and starts working as a dishwasher in a Japanese restaurant he discovers the world of Sumo where large people such as himself are honoured and appreciated.
Through Kitano (60 kilos), the restaurant owner, a former Sumo coach in Japan (who is supposedly hiding from the Yukuza in Israel), he falls in love with a sport involving „two fatsos in diapers and girly hairdos“. Herzl wants Kitano tob e their coach but Kitano ist reluctant – they first have to earn their spurs.
„A MATTER OF SIZE“ is a comedy about a „coming out“ of a different kind – overweight people learning to accept themselves.
