Summer 1999. Will joins five other idealistic graduates working for an eccentric psychology professor. They’re going to launch a website to change online dating forever.

No-one expects it to end in tragedy.

Twenty-five years later, Will gets an invitation: a dinner party. A chance to see the old gang again.

But as soon as he arrives, something doesn’t seem right.

There’s an unexpected guest. The hosts are clearly keeping a secret. And on the way in, Will is sure he heard crying.

Everyone has something to hide about what really happened that summer.

But only one of them is willing to kill to find the truth…
