It is the second series of the Big Brother franchise on Sat.1, after it left RTL II.

Twelve celebrity housemates ("promis") entered the house on Day 1.

[1] Promis had participated in tasks and matches for treats or to avoid punishments.

Housemates on the luxury floor choose of the poor housemates to join them upstairs, whilst the public will vote one of the 7 downstairs.

This year's Promi Big Brother contains two floors, each floor having its separate living areas, bathrooms, bedrooms and diary rooms.
