Today, Amik is expecting her beaver cousins for a special visit, and she can't wait to show them her home. But as the visitors arrive, Amik suddenly realizes that her little sister, Nishiime, has disappeared. Where could she have gone? As Amik shows her cousins some of her favorite haunts, the reader also learns how beavers help all the other animals in the forest: they cut down poplar trees so deer have easier access to the leaves, they create canals in streambeds that fish need to swim in during the winter months, and they build dams that form shallow pools for otters to swim in with their babies. Along the way, each animal shows its gratitude by saying "Meegwetch" (thank you) to Amik. Meanwhile, Nishiime, who can be seen hiding in the illustrations throughout the story, finally appears, explaining that she was feeling scared and shy about meeting other beavers from far away. It doesn't take long until Nishiime is comfortable with her cousins, asking many questions and planning how she will one day visit them.
