This movie was really great .the movie starts with disappearance of a school girl . and her classmates being investigated and questioned . it showed the conflict between their statement and what was later we can guess from the movie as several people seem to bully or have said something bad about the girl died. and teacher was somehow also seemed susceptable at the end of the movie dealing with some serious character remark. in this they blamed the cast which was romantically involved with the dead girl but later came to know that she was not the only person who should feel guilty as there was lot more accused. man cast felling guilty tries to commit suicide but was saved later it reveals several girl may have bad blood with the dead girl. after surviving when the mane cast enter in class she delivers a chilling speech in sign language as she was unable to speak after suicide attempt this scene was really chilling and scary . at the end it shows how in past everyone blamed her for the death she now seem to be ploting her suicide. we can get it from the last conversation of the mother of the dead girls as she says that when someone comes to ask how i died please tell everything to them . plot ends in the tunnel where she had kissed the dead girl in the past depicting that she is going to kill herself. the acting was really realistic and beautiful .the plot directing was also very well its now in my list of recommending movie . i enjoyed it really well.
