Screaming On The Inside

Seven classmates. One mansion. A silence four years in the making.
When Adrian invites his six closest classmates for a weekend at a luxury mansion, nobody questions it. Nobody notices the gate already open before they arrive. Nobody sees the photograph left on an empty floor, taken the exact moment they all said yes.
By nightfall the doors are sealed. The group is separated. And in place of answers, six envelopes, each bearing a name, each containing something its owner buried long ago and hoped would stay buried.
Someone built this house around a secret they all share.
Someone has been watching them for years.
Someone knows exactly what they did to the one person none of them have spoken about in four years.
Some secrets don't stay buried.
They build rooms.
And wait.
