The three children and Houdini travel to 1911 Paris to steal the Mona Lisa for the Butterfly Club. But they soon discover they are not the only ones planning to steal the famous painting...

Would you risk the future to change the past?

Luna, Konstantin and Aidan are time-travelling thieves working for The Butterfly Club.

When they are asked to steal a little-known painting called the Mona Lisa, Aidan can only think of one man who can make things disappear – the magician, Harry Houdini. And as luck would have it, Houdini cannot resist a challenge.

The three children and Houdini travel to 1911 Paris where they face an impossible task – stealing a painting right off the wall of the fortress-like Louvre Museum.

As Houdini prepares for the theft, a heist which will require him to pull off his greatest ever trick, the time-thieves realise that the Mona Lisa is smiling because she holds a secret. Her creator, Leonardo Da Vinci, hid mysterious codes within the painting.

The race is on to solve the puzzle in time...
