Christmas is coming to the Green house! There’s only a month to find out:

Hilja’s sister Veini claims that Christmas is just a publicity trick, but Hilja decides to prove that Christmas is real and magical. A secret operation begins, and it involves making an elf trap, lots of secret notes and spying on neighbors. Even Santa is not having it easy – he has to take part to Hilja’s lie detection test.

Many, many miscommunications are ahead before the family of the Green house can finally calm down for Christmas.

Grandpa is also closely involved in the life of the Green House. He helps Dad with the renovation, takes the kids to fish, and tells jokes.  Hilja has only seen her grandma in an old photograph. However, there are three ladies in the neighborhood who are making sure that Hilja doesn’t have just one grandma but three!

The late summer is full of hustle and bustle. Weather they are celebrating something, catching fish or making Midsummer magic it is never boring!
