During a day, they’ll need to build all together a communal strategy (for example, they can adapt the pictures they have of themselves). After the family and the impostor know each other as much as possible, they’ll get ready for the contestant’s visit (it can be a celebrity).

The visit will last 12 hours, and during that time, the contestant will live with the family trying to discover who the impostor is.

At the end of the day, if the contestant unmasks the impostor, he/she wins the prize. In case he/she fails, the family and the impostor will divide the prize between them.
