Pearls and Pigs(2003)

Overview:

When their bootlegging father ends up in jail, four twenty-something brothers need money to pay his debts to local crooks. Next, their 9-year-old half-sister is dumped on their doorstep by her prostitute mother. A karaoke set helps reveal that the little girl is quite a singer, just as a talent contest for children is coming up on national television offering more than enough money to the winner.
