Marriages!

They're 25 and are getting married today. They're 35, have been married for 10 years and are tearing each other apart. They are 45 and broke up 10 years ago and are now trying to reconcile... Three marriages, three couples going through 24 hours of a wedding disturbed by doubts and fears. These days one in three marriages end in divorce. Alright, one in three... but which one?
