One day, when the family decides to install a new stove, the cats discover a secret passageway that leads to a mysterious room. As soon as the family is out of their way, the pair decides to investigate the passage more carefully. It turns out that the mysterious room is a very cozy hideaway but the two businesscats put their heads together and come up with a brilliant plan.
