Drafting and Planning - initial plot for Trailer

My plotline for my trailer is split into four scenes. Throughout the whole trailer there will be the clock noise getting continuously louder until the alarm rings in the last scene.

1. 

PLOT =  The girl is running through the woods. She is looking behind her and stumbling over trees. She is crying hysterically and falls over a tree stump. She sees the killer approaching. She begins to whimper. 

LOCATION = Lickey hills

MISE EN SCENE = Her clothes are ripped and her hair is all messy. 

SOUNDS = All you can hear is a deep voice saying "tick tock" and ambient background sounds.

2. 

PLOT = There is a Tv appeal asking for any information about the whereabouts of the girl. There is a police officer with the parents. The parents are holding the missing person poster. 

LOCATION = Outside my house

SOUND = Parents are crying. The appeal:
                                                     Mother - "She's been missing for over two weeks.We are worried."                                                                     Father says "If anyone has any information please get in contact.                                                                                             We want her back home" 
                                                         Mother "We miss her"
                                                         Police Officer "This is not the only teenager to go missing in the                                                                                                   last few weeks.
