Passage: On 1 February 2013, Motellet Film announced on their Twitter account that they were shooting a music video for Tove Lo. On 27 February, they announced that they had finished it and posted a photo of Lo on the set. The duo directed the video, with the singer co-directing it and writing its script. Swedish website PSL premiered it on 15 March 2013, while the singer posted it on her YouTube channel two days later.The video begins with the singer recalling memories from a hangover, including images of whiskey, a shoe in a chandelier, and her making out with a man flash on the screen, particularly getting a bottle of whiskey and drinking it with him. In the following scene, Lo is seen at a tea party with four other women and the waitresses, where they drink champagne amongst an array of cakes and cupcakes. As the video flashes white, it shows a glimpse of the other women's fantasies. Then, Lo becomes drunk, takes her shirt off, smears cake on her face, pours champagne on herself and starts to dance with her guests and the waitresses. In the following scene, she makes out with the man she was drinking with. The visual ends with the singer being at home while vomiting into a sink. Scenes interspersed through the main plot portray Lo in a dark room, with mascara dripping from her eyes while doing activities such as blowing bubble gum, eating melting ice cream, and smoking a cigarette.
