“Be careful when wishing your mother-in-law was dead. She might come back to haunt you - as a dog.“ The mother of family Pitkänen, Maria, brings home a small stray dog she has found from the streets. The other family members immediately fall in love with the dog, name him Paw and decide to keep him. However, to her horror, Maria soon realizes that her recently deceased mother-in-law Anna has been reincarnated in Paw's body - and she is the only person who can see and hear her dead mother-in-law. Together, the old adversaries have to solve the family's problems, while their mutual conflict turns the family's everyday life into a flurry of crazy mishaps. Even death isn't necessarily enough to stop the holy war between a daughter-in-law and a mother-in-law.
