Never Say Goodbye (1956)

Hated by the child who was her own... and forbidden to say "I am your mother."

In present-day U.S., Dr. Michael Parker, a prominent surgeon, unexpectedly runs into his German-born wife whom he thought was dead. Victor, an artist and his "dead" wife's now boyfriend, berates Dr. Parker for "killing" her. The bulk of the story flashes back to Austria during World War II as we learn how Dr. Parker met and married his wife, and the one mistake that may have cost him his family.
