American serviceman Larry is serving in England when he goes absent without leave. After accidentally knocking out a sergeant sent to arrest him he goes on the run with a girl, Julie, riding a motorcycle around rural England. At a transport cafe, due to parallel bikes and leathers as seen from the back, she gets on the pillion of the wrong motorcycle (that of Tom Bennett), and her counterpart Irene gets on Larry's bike. Both girls realise their mistake ten minutes later.

Both couples return to the cafe to resolve it. Tom is ridiculed at the counter. Larry returns but speeds off when he sees a police car. One couple go to Sevenhills and one to Westport.

Tom heads to his Aunt Phoebe, who runs a college for young ladies in Sevenhills. Aunt Phoebe is immediately confused and thinks a love triangle is on the cards, but she treats Tom and Julie with great kindness.

Larry takes Irene to a hotel, but they are suspicious and refuse to give him a room. Eventually Ted, a barman, gives them a tip of a hotel which will take them. The night porter is surprised when they ask for two rooms rather than one.

Julie appears in Tom's bedroom in her pyjamas and they chat. He is very shy but she kisses him.

Larry heads to the docks to organise an illicit passage out of the country but his cash is in Sevenhills. He goes back to Irene's hotel room and tells her the whole story. She is sleeping nude but is very prim and polite. The next day she buys a new dress and heads to locate Sevenhills Ladies College and Aunt Phoebe. Meanwhile Julie goes clothes shopping, using some of Larry's money that he had left with her. Back at the college she treats Tom to a view of her in a basque. Larry appears at the door and a fight between the men ensues.

Irene tells Larry that she loves him. She materialises at the US Army HQ as Larry gives himself up. She claims to be pregnant by Larry (untrue) in order to lessen his court martial sentence.

It was based on an idea of a producer after he saw two people out riding.^[3] Freddie Francis later recalled:

Dear old Danischewsky whom I love asked me to do this film and I read it and I said I don't think the script is right for kids. He said you can change it. And he was serious about saying I could change it, but he didn't think I wanted to change it to the degree I wanted to. So Pam and I work on it an awful lot and we made a script which we thought was suitable for kids, when I say kids I mean a younger audience. When Danny saw it of course he was appalled, he hadn't meant I could alter it, he meant I could alter it. He meant I could change a few commas. Now I was in a spot. If I know what I know now I would have said I'm sorry Danny, I can't do it. But having gone all through the dramas, and in those days if they wanted some body to direct a film, they had to get the permission from the National Film Finance Corporation. - we are going to have so and so to direct it, and if they said no, you were out. They'd agreed that I could do it. And I thought if Iback out now I'm going to be in trouble. And so I thought I could still change it to what I wanted and I couldn't, and it wasn't very good.^[4]

Box office edit

The film received poor reviews and recorded a loss of £53,000.^[1]: 14

Critical edit

The Monthly Film Bulletin wrote: "For a film aimed at the teenage and family audience, this is a rather gauche and – despite the way it sports crash-helmets and black jackets – dated little romantic comedy. The notion of mistaken identity arising from the wearing of identical motor-bike gear is quite clever, but the plot clsewhere is even more far-fetched in detail and predictable in development, while Freddie Francis's direction lacks the necessary lift and confidence. This weakness of material and handling inclines George Chakiris to labour the pace, but Janette Scott and Alfred Lynch are touching as Irene and the naive Tom, and Athene Seyler enjoys herself greatly as the irrepressible, anti-Square, Aunt Phoebe. It is the cast, in fact, which enables the film to be indulgently enjoyed."^[5]
