Three estranged brothers return to the Swedish lakeside cottage where, more than two decades before, an unspeakable accident forever altered their family and changed the course of their lives. There is Nils, who couldn't escape his suffocating home soon enough, and Pierre, easily bullied and quick to lash out. And then there is Benjamin, always the family's nerve center, perpetually on the lookout for triggers and trap doors in a volatile home where the children were left to fend for themselves, competing for their father's favor and their mother's elusive love. But as the years have unfolded, Benjamin has grown increasingly untethered from reality. And among the brothers a dangerous current now vibrates. What really happened that summer day when everything was blown to pieces?
