Erin Rines is caught in continuous peril while investigating the concealed murders. She plows her way through mud and bear country in her large, Northern Ontario community to care for patients, over time finding more than one partially buried body.

The surrounding earth of both town and forest becomes saturated with the steady, spring rains, causing the muddy ground to erratically move in a compulsive, sometimes deadly slide. Will a persistent and indiscriminate murderer lure Erin toward further danger and cause the sodden earth to swallow her and others, some of them not so innocent, into a surplus of obscure graves?
