On Thin Ice.

It's Christmas Eve in Helsinki. Young taxi driver Samu is working to escape a family Christmas with his fiancé and baby. At the airport Samu picks up a fascinating customer: a Finnish mercenary Hans, who has returned to Helsinki after an absence of 20 years. Hans hires Samu to go on a mission with him: to find Laura, the daughter of his recently deceased best friend and brother in arms. The quest to find Laura leads the men around the wintry city, to places and people from Hans's past. As Samu watches Hans confront his past, he begins to open his eyes to his own future. When the eventful mission reaches its end, both of the men's lives are forever changed.
