After the sudden death of their parents, the three Baudelaire children must depend on each other and their wits when it turns out that the distant relative who is appointed their guardian is determined to use any means necessary to get their fortune. Violet, Klaus, and Sunny Baudelaire are intelligent children. They are charming, and resourceful, and have pleasant facial features. Unfortunately, they are exceptionally unlucky.

Violet, Klaus, and Sunny Baudelaire are taken in by a series of oddball relatives and others after their wealthy parents are killed in a fire. The first to take them in is the dastardly and cunning Count Olaf, who is only interested in their inheritance.

As their outrageous misfortune continues, the Baudelaire orphans are shipped off to a miserable boarding school, where they befriend the two Quagmire triplets and find that they have been followed by the dreaded Count Olaf.

On the run after being falsely accused of murder, the three Baudelaire orphans find themselves in the Heimlich Hospital, with the evil Count Olaf in close pursuit.
