The trailer opens to the non diegetic soundtrack "Worth it" by Fifth Harmony, which is a song that recently has been featured in the pop charts, this immediately targets the younger population of the receiving audience, the song is upbeat also which casts a joyful and party mood over the picture already, making the audience sense it as light-hearted. The scene then opens to a low angle panning medium shot, showing two girls, one tall with brown hair, who's mise en scene shows her to be fashionable yet a cute girly girl type, Whereas the other curvier girl has blonde hair, and mise en scene shows her wearing all black with a leather top, making her appear more promiscuous and at a complete contrast to the brunette girl, which is proved diegetically, when the brunette (Alice) states that she's going home, and the blonde girl (Robin) says she cannot "waste a night in New York City".
As Robin continues to speak, the editing creates a fade to an establishing shot of the Brooklyn bridge and the city following it, showing that possibly Alice is new to New York, and is getting help through Robin on how to live there. Then cutting to a Birdseye view of the city at night, the chorus in the soundtrack starts with the sound level increasing, showing the audience that this film will show a lot of partying, as we then cut to a medium shot of Robin clinging on to the side of what appears to be a pylon as she grasps a bottle of champagne with the other hand. Conforming to the stereotype that the funnier friend has a bad influence on the nice and quieter main character, this is proven when we see Alice dancing in a large crowd filled shining pink and blue LED lights onto her face both connoting fun and lighthearted times, but also the colour theme of the films poster.
Then cutting to a medium shot of the two girls walking in to a bar, Robin diegetically tells Alice she is going to teach her "how to be single", showing the the films title used within the trailer, showing the audience that Alice is an introvert who Robin is trying to get to break out of her shell and live the drunken single life with her. As Alice tries and fails at trying to get men to buy her and Robin drinks in a shot reverse shot exchange with a large group of business men, this is known due to their smart business attire, we see that Alice is really inexperienced at talking to men, and shows the audience she hasn't been involved in the single life for a while.
We then cut to a high angle wide shot of Robin dancing with a large crowd watching her, Robin's mise en scene shows her wearing a black dress with an electric light up arrow pointing down, confirming that she is a promiscuous character and conforms to the stereotype of a "Ladette", who behaves in a way that the majority of men would. The trailer then focuses on this as we cut to another medium naturalistic style shot of a man in a silk dressing gown as Robin walks around the camera and screams as she sees him causing him to jump, The shot reverse shot exchange shows Robin to be clueless to the fact that she's in someone elses apartment and states she "cant remember" what happened last night, Which again shows the comedic value of her character and shows a lack of seriousness which may prove to wear thin within her and Alice's friendship.
Then cutting to a close up shot of a stereotypical rugged, handsome man telling Alice she's pretty, and that she'll find someone in New York,to which she blushes in another close up shot, showing the audience a possible love interest between the two. This is later come back to within the trailer when we see the two passionately kiss in a medium wide shot.
Robin continues to be portrayed as a bad influence on Alice, as shown in a medium circulating panning shot the two's mise en scene wearing the same clothes as they did the previous night with sunglasses and matted hair, suggesting that they never went home the night before and are hungover, the bewildered two then venture into hurrying across the city to get to work in twenty minutes.
Again targeting a younger audience due to the medium shot reverse shot exchange between Robin and Alice at work, when discussing text messaging, through technological phrases such as "emoji", showing the audience that many relationships are impacted heavily by technology, such as when Robin says she has to wait 4 hours before Alice can reply to a boys text. Most older adults of 40+ probably wouldn't understand the humour of this as much as someone younger would.
We then cut to a close up shot of Alice smiling, then cut to another close up of a man smiling back at her, showing that Alice has multiple love interests, and therefor get the audience to assume that Alice is changing into another version of Robin, though this does not appear to be a bad thing as she appears to be happy, whilst these shots are seen we can hear Alice non diegetically say "The thing about being single is, you should cherish it", suggesting that she changes her opinion through having help from Robin and others around her.
The trailer then closes on a sequence of the actors as they are credited and clips of them are shown after, then closing on the films title "How to be Single".
