Breakup at a Wedding (2013)

Synopsis

On the eve of their wedding, Alison gets cold feet and decides to break up with her fiancé Phil. But rather than face the embarrassment of calling off the ceremony, Alison suggests to Phil that they proceed with a sham wedding. Phil is more than game to try, secretly hoping that a surprise gift he has for Alison will ultimately change her mind. Yet once the guests begin to arrive, more complications ensue than either of them could have ever imagined - even if they did know their wedding was bullshit.
