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.

In the perilous Mortmain Mountains, Klaus and Violet Baudelaire meet another well-read person, who helps them try to rescue Sunny from the villainous Count Olaf and his henchmen as they all near "the last safe place."

The woeful saga of the Baudelaire orphans continues as evil Count Olaf discovers their whereabouts at Esme Squalor's seventy-one bedroom penthouse and concocts a new plan for stealing their family fortune.

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.

Under a new government program based on the saying "It takes a village to raise a child," the Baudelaire orphans are adopted by an entire town, with disastrous results.

Lost at sea, the Baudelaire orphans, along with the evil Count Olaf, wash up on the shore of an island populated by an oddly placid group of inhabitants, and they try to decide whether or not they are truly safe.
