" One of Us Is Lying is the story of what happens when five strangers walk into detention and only four walk out alive. Everyone is a suspect, and everyone has something to hide."

This is what the synopsis says, and that makes it seems like it's a really gripping and thrilling murder mystery.
But there's not much mystery anyways.
The clues are randomly thrown here and there.
Nothing (at all) happens in the first half, but in the second half, stuff happens and it suddenly the whole "mystery" is solved conveniently.
This was just about average.
