An Australian researcher transforms her (Mundane?) life after meeting a Scottish SAS captain in London, and making a commitment to meet him again in five years time, when he retires. (She will need to convince her overprotective family if she really is to live happily ever after.)

Rubbish examples, but you get what I mean.
