This is the blurb from Big Fish:
Syberia - Part 3
[Note: If you own the original Syberia, this is the same adventure.] Continue the journey in Syberia: Part 3. Kate Walker is in search of the last remaining heir of a manufacturing estate, Hans Voralberg, who has mysteriously disappeared into the wilds of Syberia! Kate is unsure whether to continue her journey which has taken her so far away from home, but the experience is bringing out an adventurous spirit within her that she never realized she had. Follow the trail to Komkolzgrad and get closer to solving the mystery.
Looking at the screenshots - it looks like the ending part of Syberia 1 released in 2002 - from Komkolzgrad to end.
So if you played part 1 and part 2 - this is a continuation of that story.
Also I will move this thread to discussion forum.
Part 1, part 2 and part 3 are all parts of the original Syberia 1 released in 2002.
You still have to play the original Syberia 2 released in 2004.
I wonder how many parts will Anuman chop that game up?
