"The Accidental Husband" centers on Emma (Uma Thurman) a successful but uptight relationship expert with a hit radio show and an upcoming book. She is serious and sensible about the issue of love and gives frank, 'on the nose' advice to women on how to find the right man without wasting time on the wrong ones in between. Emma believes she has met her own perfect match in Richard (Colin Firth) a successful and conservative publishing executive.

Of course matters of the heart are never as clean cut as Emma believes them to be! Just weeks before her wedding Emma discovers she is somehow already married to Patrick (Jeffrey Dean Morgan) an irresponsible but charming neighborhood fireman with a big secret …the marriage is no accident.
