An old man dies, leaving his property to his grandson Billy and his Hong Kong born god-daughter, Lydia. Lydia and Billy are forced to stay together because in his will he states that whoever lives in the house with their family shall inherit the property, along with a tidy sum of money. The only problem is that Lydia is the exact opposite of Billy. She is a little disorganised and relies heavily on post-its to remind herself of appointments while Billy is a control freak and absolutely neat. Adding more laughter to this sitcom is Billy's son, Max, and Lydia's two children, Apple and Jordan.
