As the episode opens, Anna is trying to phone her friend Helen, but she can't get through. The operator is having trouble connecting the call because everyone in town is in a panic about two murders that have recently taken place. The "Lipstick Killer" has struck twice, and the town is terrified he will strike again.
Anna wants Helen to come and stay with her because she doesn't feel safe alone in her home. Helen finds the request odd because the two of them haven't spoken for four years, but she eventually agrees to come over. Helen knows that her old friend Anna is a bit strange, but she soon realizes how much stranger Anna has become since she last saw her.
"Summer Night" was also presented on the Suspense television show on February 19, 1952, but that episode is not known to be available at this time.
