In This Our Life is a 1942 American drama film starring Bette Davis and Olivia de Havilland as sisters and rivals in romance and life Stanley and Roy Timberlake. This was the third of six films in which de Havilland and Davis starred together. The film was directed mostly by John Huston, in his second film, but when Huston was called to a war assignment, an uncredited Raoul Walsh completed the film. The screenplay was written by Howard Koch based on the 1941 Pulitzer Prize-winning novel of the same title by Ellen Glasgow.

Completed in 1942, the film was rejected in 1943 for foreign release by the wartime Office of Censorship because it deals truthfully with racial discrimination in its plot.

In Richmond, Virginia, Asa and Lavinia Timberlake have two daughters with male names, Roy and Stanley. Roy, a successful interior decorator, is married to Dr. Peter Kingsmill. Stanley is engaged to progressive attorney Craig Fleming. One evening, with days until her wedding, Stanley runs off with her sister's husband Peter. Craig becomes depressed, but Roy decides to keep a positive, although somewhat hardened, attitude. After Roy divorces Peter, he and Stanley marry and move to Baltimore.

After some time, Roy encounters Craig sitting dejectedly on a park bench. Observing his sad, neglected appearance, she encourages him to embrace life, and they begin dating. Roy refers a young black man named Parry Clay to Craig, who hires him to work in his law office while attending law school. Parry is the son of Minerva Clay, the Timberlakes' long-time housekeeper.

Roy and Stanley's uncle, William Fitzroy, had doted on his niece Stanley and gave her expensive presents and money. Fitzroy is upset that she has run off with Peter. He says that he will send Craig some of his legal business if he agrees to stop representing poor clients. When Craig refuses, Roy is impressed and agrees to marry him.

In Baltimore, Stanley and Peter's marriage suffers from his heavy drinking and her excessive spending. Deeply depressed, Peter commits suicide. Shaken, Stanley returns to her hometown with Roy. After she recovers, Stanley decides to win back Craig. While discussing her late husband's life insurance with Craig at his office, Stanley invites him to join her later for dinner. He does not go to the restaurant, and she gets drunk. While driving home, she hits a mother and her young daughter, severely injuring the woman and killing the child. In a panic, Stanley drives away.

The police find Stanley's abandoned car with blood on the front end and question her. She lies, telling them that she loaned her car to Parry on the night of the fatal accident. On the strength of the accusation, Parry is jailed. However, Roy suspects that Stanley is hiding the truth, and Parry's mother said he was home with her all evening, studying. Stanley refuses to admit her responsibility, even when Roy arranges for her to see Parry at the jail. Stanley tries to convince Parry to confirm her story. Later, her ex-husband Craig confronts her once more after questioning the bartender at the restaurant, who remembered seeing Stanley. Craig knows that Stanley left the restaurant, drunk, just before the time of the fatal accident. Craig plans to take Stanley to the district attorney, but she flees to Fitzroy's house and pleads for his help. However, having just learned that he has only six months to live, Fitzroy is too distraught to do anything for Stanley. Stanley is chased by the police; she crashes her car and dies.

Craig is attempting to comfort Roy as she anxiously frets about how to help her sister, when the authorities call to inform them that Stanley died.
