Five remarkable kids live in a little corner of Singapore, and together they call themselves The Curious Four… plus one. Ava Tan is fast, sharp, and always spotting tiny clues others miss.
Arjun Reddy is calm and clever, solving tough puzzles with that quiet, confident smile.
Hanna Park sees the world differently, sketching plants, insects, and every strange detail that might become a clue. Mateo Rivera brings the fun — he can turn even an ordinary walk into an adventure.
And tagging along is Mira Reddy, Arjun's nine‑year‑old sister. She's super smart, full of curiosity, and never afraid to poke her nose into anything interesting.
These five friends hang out together, explore new places, and dive headfirst into exciting adventures — solving mysteries, cracking clues, and having the kind of fun every pre‑teen dreams about.
So what adventure are they racing into this time?
Ava finds a message in a bottle washed up on the shore. Inside is a strange drawing… and a mysterious note. The Curious Four (and Mira) solve the first clue — but it only leads to another, hidden deep inside a forest no one ever visits.
Are they walking into danger? Are they safe? Or is this mystery bigger than they imagined?
Thrills, chills, and clever twists await as these brilliant kids weave through a maze of clues.
