When Gabriel moves to a housing project in Södertälje, he meets Marko, who is the king of the errand boys. Marko takes Gabriel under his wing and a friendship soon develops before Gabriel realises how dangerous it is. When a spectacular mistake is made, anger is created higher up in the criminal hierarchy. Taelgia tells the story of families, police and criminals caught in a crossfire of loyalties, demands and guilt in the same neighbourhood.
Elisabeth and John John are raised in the same city, yet they live light years apart, separated economically, socially and culturally. That is until the day they start in the same high school class.
