Dink has four sisters who can make his life miserable, but not even four sisters can keep him from being the happiest boy alive. He is finally getting his very own horse, a real cowpony. His dream is right on track until his sisters take over. His perfect cowpony somehow turns into an old, broken-down, half-starved, retired circus horse. Excitement quickly turns to disappointment and resentment until Dink learns the meaning of love, loss and family even one full of girls which can be the nicest thing in the world.
