A magical adventure inspired by the Chronicles of Narnia, Walt Disney animated musicals and the parables by Jesus Christ "Strawinsky and the Mysterious House" tells the story of four talking animals that discover a hidden mansion in the middle of a secret forest. They start exploring the house and encounter strange inhabitants such as a depressed cello, a manic troll and an overweight creature that is addicted to the books in its basement. As Strawinsky - the hero of the story - tries to solve the mysteries surrounding the house, his friends get trapped in the underground library. It's up to Strawinsky to find a way to break the dark spell and help his friends to escape from the evil lurking within the mysterious house.

Heavily based off a novel published in 1678 by John Bunyan, the film follows a man named Pilgrim, who goes on a journey to be cleansed of his sins and enter the celestial city. Along the way, he encounters hardships and red herrings.
