The third sister and brother lost their parents in a fire and inherited a large inheritance left by their parents. Because he is still young, the money can only be used when he is of legal age. As a result, the third sister and brother were temporarily taken to the distant relative Olaf (Jin Carrey Jim Carrey) home, by Olaf to raise. Sister Violet (Emily Browning Emily Browning) is an inventive elf, while his brother Klaus is knowledgeable and authentic. The youngest child has sharp teeth, ah, ah, This time the third brother and sister fell into the trap of Olaf and were targeted by this greedy relative for the inheritance. They were in danger again and again, and it seemed that Olaf had to kill them. So they fled to the home of their uncle, a biologist, but it was full of snakes, which was rather scary. To make matters worse, Olaf followed like an inextricable shadow. The three children continued to flee, and when they found that their aunt's house was not the place to go, they decided to stand on their own feet and fight the evil Olaf to the end.
