context: For the only time in his many films, Alfred Hitchcock starts this picture talking to the camera and says that "every word is true" in this story.
  Manny Balestrero (Henry Fonda), a down-on-his-luck musician at New York City's Stork Club, is in a money crunch. His wife, Rose (Vera Miles), needs to have her wisdom teeth extracted at a cost of $300, but the couple does not have that much money. Though he has already borrowed against his life insurance policy, he goes to the life insurance company to attempt to take a loan out against Rose's policy. He is immediately recognized by the clerical workers in the store as the man who had twice held up the insurance office. They inform the police, and he is taken to the 110th Precinct by detectives. Without being told why, Manny is instructed to walk in and out of a liquor store and delicatessen, both scenes of a robbery earlier that year. He is then asked by police to give a handwriting sample, writing the words from the stick-up note at the insurance company. Manny misspells the word "drawer" as "draw"âthe same spelling mistake the robber made in the note. After being picked out of a police lineup by the women from the insurance company, he is then arrested and charged with robbery, and his family finds out that he will be in court on the following morning.
  Attorney Frank O'Connor (Anthony Quayle) sets out to prove that Manny cannot possibly be the right man: at the time of the first hold-up he was on vacation with his family, and at the time of the second his jaw was so swollen that witnesses would certainly have noticed. Manny and Rose look for three people who saw Manny at the vacation hotel, but two have died and the third cannot be found. All this devastates Rose, whose resulting depression forces her to be hospitalized.
  During Manny's trial a juror, bored with the minutiae of one witness's testimony, makes a remark which prompts the judge to declare a mistrial. While Manny is awaiting a second trial he is exonerated when the true robber is arrested holding up a grocery store. Manny visits Rose at the hospital to share the good news, but as the film closes she remains clinically depressed; a textual epilogue explains that she recovered two years later.
question: What was Manny doing the day of the second robbery?
answer: Recovering from a swollen jaw.
