The summary describes a wolf pack led by the alpha Sariak that encounters a new human city being built near their territory. Sariak visits the sled dog pack owned by Bill to learn more about the city. Sariak then has the idea to harness the sled dogs to buildings in the city to try and pull them down, hoping this will make the humans leave. Sariak and the wolf pack work with the sled dogs to carry out the plan under the cover of darkness.
