Richard Moresby faces a dilemma when his wealthy wife, Una, falls under the spell of Dr. Sing, a mystic who claims human spirits return as animals. When Una vows to leave her fortune to Sing’s temple, Richard stages her death as a suicide, securing his inheritance. But his confidence falters as animals begin appearing around his home — a barking dog, a persistent raccoon, intrusive birds. Is it guilt, paranoia, or did Una truly mean it when she swore she’d be back?
