We are immediately dropped into the action as the film begins, the scene is shown as a barren wasteland and a sandstorm is starting. Lana is running to the bunker as fast as she can and her breathing is fast, this builds tension and fear, it also helps to make her seem more vulnerable and human which makes her more relatable to by the audience. As the airlock cycles we see that she is wearing a gas mask, this shows us the danger of the world outside which helps to explain later events and depresses the audience by showing them the sorry state the world is in.
The scene shifts to a medium shot of a tape player in the desert which begins to play a sad song, as it does the title 'Replay' writes itself into the sand. The music and setting again helps to establish the mood of the film which is very downbeat.
A long shot of Lana inside the bunker shows the audience what everyday life is like for her, the darkness and lack of activity shows how depressing life in this post apocalyptic world is like. She enters her living quarters where we see Theo for the first time, his friendly greeting and boyish nature helps to brighten up the scene and gives the viewer hope that better things will come later. Lana shows her latest haul of valuable objects to Theo including a tape player and switches it on, the sound of children playing fills the room. He tries to listen to some more of the recording but Lana takes it away since she needs it undamaged in order to sell it. Theo is annoyed at not being allowed to listen and asks if he can accompany Lana on her next trip but she won't allow him since he is too young. This shows us life from Theo's point of view and illustrates how bored he is by the confines of the bunker.
During the conversation between Lana and Theo most shots are medium or close ups which are used to show the emotions of the characters, allowing the audience to better understand them. There is also a low drone of air filtration equipment throughout the scenes which adds to the atmosphere of the bunker, showing how dependent the humans are on the surviving technology in order to survive themselves. Theo also has an artificial leg, this shows the audience how vulnerable he is, making them fearful for his well being.
As Theo goes to bed he takes one last look at the tape player and some downbeat non-diagetic music plays, this tells the audience that he still feels unhappy about not being able to listen to it more. The non-diagetic music becomes diagetic music playing from a radio as the scene changes to the morning which keeps the scene transition smooth. Lana finds that Theo has left the bunker and sets off after him. We see Theo outside an abandoned town in the desert, the echoing wind coupled with the downbeat music makes the scene very upsetting. The harsh sun has bleached colour from the landscape and the lack of life completes the vision of total destruction which adds to the depressing atmosphere. Theo plays the tape and sounds from the past are injected in to the present, he looks around trying to find a source but all he finds are ruins which adds to the feeling of loss the viewer feels.
Theo eventually ends up at a school and listens to the sounds of children playing. As he listens the sounds seem to come to life, the music also becomes more positive and uplifting. Spectral children can be seen playing, they are imbued with a colourful haze which breathes life into the surroundings. Lana is trying to find Theo in the town which reminds the audience of the danger he is in. Theo sees his reflection in a broken window and the music becomes darker once again, with him wearing his gas mask he looks very strange to the colourful children. He decides to take of his mask and breathes in the air, after nothing happens to him the audience feels relieved. As he drops the mask his artificial leg repairs itself and the world around him changes to that of the past. The ensuing crescendo of colour is joined by equally uplifting music, the lack of danger and the abundance of life fools the audience into thinking all is well. Almost immediately afterwards Lana arrives and finds Theo lying in the yard, most of the colour has left the scene and the music has become sombre. This sudden change will shock the audience after the happiness of the previous scene.
There is a long shot of Lana kneeling next to Theo which pans slowly down to see the tape player playing the now haunting sounds of children. As the tape finishes all sound and music stops except for the echoing wind.
