Singing sensation Deanna Durbin stars along with Edmond O'Brien, Don Taylor and Ray Collins in the screwball comedy, For the Love of Mary. When Mary Peppertree (Durbin), a White House telephone operator, breaks her engagement to marry an attorney (Jeffrey Lynn) for the Justice Department, it causes a stir and encourages two new admirers, David (Taylor) and Tom (O'Brien), to pursue her. Mary's romantic entanglements soon become the talk of the White House and even the President of the United States and four Supreme Court justices try to play Cupid for her. Noteworthy as Deanna Durbin's last film (at the age of 27), this engaging, energetic classic also features such songs as "Moonlight Bay", "Let Me Call You Sweetheart" and "Big, Wide, Wonderful World."
