Das Ende der Eiszeit (2011)

Mika encourages his lover and management partner in Oslo's leading virtual bookshop, Annika Sörenbrandt to return to her fjord home village Fjærland to help her 25 years-estranged mother Pernille who is disabled by a fall from running the country's oldest paper books shop with her second partner. Thus Annika discovers her illegitimate half-brother Henrik still loves at home, suffering from a severe autistic condition. The siblings bond, yet Annika isn't ready to forgive Pernille's adultery and choosing Henrik over her, as her late father refused to stay with the bastard. Henrik insists to join her a while back to Oslo, professionally minded by Ole.
