10 average people - Andrew, Anna, Caroline, Craig, Darren, Melanie, Nichola, Nicholas, Sada and Thomas - enter the Big Brother house, a space-aged bungalow filled with cameras and microphones to record their every move and sound. During their first few days in the house, the new housemates get to know each other, Anna reveals she is a lesbian, Mel and Andy get cosy, the group are set their first food challenge - a pottery contest - and Nichola uses the clay to decorate the house walls with images of her naked body. Before long, many others join in, too.
