Would you like to know How to Possess a Cat?
All is revealed when Maximilian, an over 100-year-old soul currently residing in the historically French part of St. Louis, begins a new adventure by taking up residence in a three-legged cat named Maggie. Having traveled many years in a variety of feline companions, each of which can hold up to nine "lives," Max hopes to have finally found peace and quiet within Maggie, whose handicap makes her less desirable to other wayward souls. Max's newfound solitude is quickly disrupted upon the tragic suicide of Sarah, another resident in the newly rehabbed apartment building where Maggie and Max live. After discovering the secret crime behind the Sarah's death when her soul is also taken in by Maggie, Max risks his own existence in an attempt to bring closure to the young woman's grieving mother.
