Widowed factory hand Len Spud becomes a billionaire after inventing a new kind of toilet roll, Bumfresh, buying a palatial mansion, complete with staff and celebrity butler Warwick Davis, for himself and twelve-year old son Joe. Joe feels alienated by the new life-style, trying to fit in at the local school by keeping his wealth a secret and wary of Len's gold-digging new girlfriend Sapphire Diamond. Unfortunately Len reveals Joe's identity and he is surrounded by greedy new 'friends', with his one true friend Bob feeling betrayed and refusing to take his money. Consequently Joe decides to use his money to do good but then something happens to provide Len with a wake-up call to make things better between him and his son.
