It was an ordinary Tuesday night in Ridgefield. The streets were silent, the houses were dark, and the only sound was the faint buzz of computer displays and cell phones. But the locals had no idea that a serial killer was among them, using the very gadget that linked them to spread dread.

It all started with a simple post on the famous social media platform 'FriendZone.' 'Who's up for a game of hide and seek?' said the post. Thousands of people read the post, but only five reacted, assuming it was a harmless prank. They had no idea it was the beginning of a nightmare.

The next day, five seemingly unrelated individuals were brutally murdered.
