In the wake their mother's death, three estranged brothers return to the lakeside cottage where, over two decades before, an unspeakable accident forever altered their family. There is Nils, the oldest, who couldn't escape his suffocating home soon enough, and Pierre, the youngest, easily bullied and quick to lash out. And then there is Benjamin, always the family's nerve center, perpetually on the look-out 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, frozen in place while life carries on around him. And between the brothers a dangerous current now vibrates. What really happened that summer day when everything was blown to pieces?
