Twisted

When two girls, Lacey and Jo, were playing in a garden, their best friend, Danny, came to them and he said "I've just killed my aunt".

This drama began when Danny was released from juvenile detention and entered school where Lacey and Jo go 5 years after this incident. Two girls are estranging each other. Jo had been annoyed at first she met him again, but they have returned to friends gradually. But Lacey tried to keep distance from him because she was scared of him as well as other students because of the incident. To make matters worse, that night he entered the best friend of Lacey, Regina, was killed.

The interesting points of this drama are that 1) Why did he kill his aunt. 2)Though the prime suspect in murder of Regina is Danny, did he kill her? 3) What will happen between Danny and the students who hates him and ridicule Jo, and 4) Danny seems good boy and doesn't seem hurt anyone else, but is he really sociopath?
