When Mousy moves in with Buck, she finds their life isn't quite like she thought it would be? Buck seems to want to control everything she does. He starts asking her strange questions: "Isn't it a little late for you to be getting home?", "Are you hiding something from me?", "Wear this - don't you want to look pretty for me?". As time goes on, Buck becomes more possesive and, while Mousy seems to shrink, Buck seems to be transforming from a mouse to a cat. Mousy must find the courage to escape the burrow.
