The film opens from a vantage point over the rooftops, showing some of the morning occurrences through the windows of the houses. A young man dressed in a fashionable mod style prepares for the day from his rooftop flat and cycles around to the theme song. He then takes his bicycle and descends to the streets of the leafy suburbs. Cycling down some steps he crashes into the bike of a little girl and is knocked unconscious. She stands over him showing her pigtails, glasses and braces and gazes at him, clearly besotted. The man awakes and asks the girls name. She tells him she is called Kate. He bids her farewell and cycles off, she follows behind. As he cycles the man sings a song about how he does not envy the responsible, monotonous lives of older people. The girl blows a raspberry as she passes a queue of people at the bus stop; this starts a disagreement between the people at the stop which ends with a food fight. Cycling into a park, the man looks back to see if Kate is still following him, and loses control of the bike, running away down a hill and crashing through a large advertisinghoarding. Climbing out, he is struck by the face of a model, "Julie" on the poster advertisingRaleigh bicycles. He sings a song professing his love for her and picks flowers to give to her image. Kate tries to attract his attention but he is transfixed by the beautiful model. He eventually rouses himself from his stupor and cycles away. Kate blows a raspberry at the poster then follows him.
The man arrives at his workplace, a printers, opens the post which has arrived, and finds one parcel is a photographic portrait of Julie. He sits gazing at it, while the camera pans across the street. It happens that Julie is at a society party in the building there. She sings a song about how pampered and cloistered her world is, and how she wants to find a true love. She walks out of the building, crosses the street and looks at the photo of her which has now been hung in the printers window. The man is gazing at it still, and recognizes her. She smiles at him uncertainly at first, but then with more self-assurance, and they kiss through the glass. Before the man can go outside and meet Julie, she is whisked away in a limousine to a fashion shoot where she poses in various 'groovy' outfits in a park, looking unhappy and distracted, wondering where the man she just met is. He cycles through the park looking for her and when he finds her sings his love song again. They walk off hand in hand. The little girl watches them from a hill and looks sad. Then a little boy cycles up, sees her, smiles and expresses his attraction for her and makes her smile. They cycle off together.
