De Gouden Kooi (The Golden Cage) is a Dutch reality competition that premiered in 2006 on Tien.
Natasia, who had left behind her two young kids, refused to return home when her boyfriend who cared for them asked her to.
Some participants started (loveless) sexual relationships, which led to jealousy and much verbal abuse.
Because there are no nominations or votings off like in Big Brother, psychologists assume that harassment and bullying will be the only ways of getting rid of one's rivals and obtaining the reward.
The producers rather expect that housemates will leave if they experience homesickness or family-complications will occur (death, birth, or sickness).
