The Brisby home begins to sink into a mud puddle and the rats are unable to raise it. Mrs. Brisby's will to save her children gives power to the amulet, which she uses to lift the house and move it to safety. The next morning, the rats have departed from the farm with Justin as their new leader and Timothy begins to recover. Jeremy soon meets Miss Right, another crow who is just as clumsy as he is, and they fall in love.
