The majority of the danish youth starts to drink at the age of 12. Brain scientist Peter Lund Madsen relates the impact of alcohol on the brains of children, while Jakob Demant, from the centre for alcohol and drug research, explains why young girls are the heavy drinkers of today. Lucas’ mom thinks it is the parents job to teach their children how to drink responsibly, so she buys alcohol with her 12-year old son. Oscars’ mom turns the blind eye on the boozing of her 14-year old son, while a group of 14-year old girls tries to compete with the older boys in drinking competitions.
