The one and only love (Lyubov odna)

Sergey has been asking Olga to marry him for seven long years but she is reluctant and with good reason. Olga has been engaged before and her previous fiancé, Denis, left her at the altar. Apprehension aside, Olga is certain that she loves Sergey and feels she has kept him waiting long enough so she finally accepts his proposal.
Just before her wedding day, Olga goes on a business trip where she unexpectedly meets Denis who is now a well-known writer. Suddenly, her old feelings for him come flooding back. Will she choose the right man or will she make the same mistake twice?
