The programme centres around Leo, the ex-boyfriend of businessman Roman Pretty's middle daughter Nikki, who still works and lives with the family. Nikki's new boyfriend, Seb, has a shady past, which Leo tries to reveal to the Pretty family but usually ends up making himself look a fool. His best mate Jase is married to the eldest sister, Jenny, and is constantly attempting to get away from her and their new-born daughter.
After a complaint from Roman in a restaurant, Japanese chef Mr Hokkasawa loses his job. He had sworn that he would never use his sword again but later takes the job of the Pretty family gardener. Mr Hokkasawa is always plotting against Roman, but falls for his youngest daughter Kelly. All the characters live in a large house owned by Roman, which is where the majority of the story is set.
