A Letter to Three Wives

Just as they are about to take a group of underprivileged children on a riverboat ride and picnic, Deborah Bishop (Jeanne Crain), Rita Phipps (Ann Sothern), and Lora Mae Hollingsway (Linda Darnell) receive a message from Addie Ross informing them that she has run off with one of their husbands. She, however, leaves them in suspense as to which one. All three marriages are shown in flashback to be strained.

Deborah grew up on a farm. Her first experience with the outside world came when she joined the Navy WAVES during World War II, where she met her future husband Brad (Jeffrey Lynn). When they return to civilian life, Deborah is ill at ease in Brad's upper-class social circle. Adding to her insecurity, she learns that everyone expected Brad to marry Addie, whom all three husbands consider practically a goddess. Read more on Wikipedia.
