The departure of his mother leaves Ray (Alex House Alex House) with a brother Morri (David Randall David Rendall), an arrogant sister Lisa (Tatiana Maslani Tatiana Maslany), a small house and a cat named "Sir". In desperation, Ray moved back home from his apartment and began to live together with his brother and sister. The eccentric Lei who is fond of the model does not adapt to it, of which nothing is more difficult than the grandmother who was picked up by his mother from Japan (acted the role of Seijin Sako). Grandma doesn't speak English. She sits in a daze at the window all day. She spends a lot of time in the toilet every morning. When she comes out, she sighs and likes to watch the air guitar show. Four people and a cat living under the same roof gradually intersect in the running-in. Ray began to call more and more, Morri became interested in the sewing machine left by her mother, and Lisa paid attention to the personality man in the poetry class. Grandma who can't speak English can feel their hearts magically and can make delicious fried dumplings. Ray also used the money he had originally planned to buy a model to buy a Japanese toilet. The whole family because of the outside.
