when a women can't get over her boyfriend/husband a friend suggests that she use this program/site where they use all the information that the dead person posted online and use it to create a profile. the women is sceptical but finally tries it, she goes from talking to him ovver the computer by IM to over the phone to getting a body she had to put in water that he turns into well the internet version of her boyfriend/husband
