When Liv Lerner (Kate Hudson) and Emma Allan (Anne Hathaway) were girls they both attended such an impressive wedding at New York's landmark Plaza Hotel, they swore that, when the time came, they too would celebrate their nuptials there.
Now, 20 years later, and after saying 'yes' to their respective fiancés, they've instructed their wedding planner to book the ceremony of their dreams. But, a clerical error results in both being given the same slot - and neither is willing to concede.
Instead, their friendship is jettisoned as they resort to underhand tactics in a bid to sabotage each other and fulfil their fantasies...
Also starring Candice Bergen, Chris Pratt and Bryan Greenberg.
