Six friends.
Six cherished secrets.
One unsolved murder.

Now someone has brought them all together to find out what really happened that night. Someone is determined to uncover their secrets and catch the real killer, to make the guilty pay. Now they all become targets because one of them is either the real murderer or knows more than they say. But could it be that someone became a killer but doesn't remember it?
So what really happened that night?
