Thora, August and Hugo come from different worlds. One is an art school dreamer, one a wealthy scion of the old-world elite, and one an ordinary boy from out of town.
But over the course of two sky-blue summers in Stockholm, they are drawn together magnetically. Years later, Hugo is long estranged from Thora and August when their daughter knocks on his door. She has questions about her parents which she believes Hugo can answer – and the memories of those luminous days of youth come flooding back.
