You Can’t Get Away with Murder

Johnny trusts Frank and wants to prove himself in the criminal underworld. Frank asks for a gun to use in the pawnshop robbery, and Johnny borrows it from his sister Madge's fiancé Fred Burke without considering the consequences. Johnny believes the plan is simple, a quick robbery that won't go wrong, but he underestimates how dangerous Frank is.

Earlier, Johnny defies his sister Madge's warnings and teams up with Frank, showing his willingness to choose his criminal mentor over family.

When Frank kills the pawnshop owner, he leaves the gun at the scene. Since the gun belongs to Fred Burke, investigators link it to him. Fred's alibi is dismissed as unreliable, and without Johnny's testimony to explain how his gun was stolen, Fred is arrested and convicted of murder. He is sentenced to Sing Sing's death house despite being innocent.

Frank repeatedly warns Johnny that if he confesses, both of them will face consequences for the murder and the gas station robbery. Johnny is torn between guilt over Fred's impending execution and fear of his own fate. His loyalty to Frank, combined with the pressure to avoid his own execution, keeps him silent, though the moral weight slowly destroys him.

On the day Fred is set to be executed, Frank and Johnny stage a jailbreak. During the chaos, Johnny writes a confession explaining he stole the gun and Frank did the shooting, leaving it for Pop to find. Frank discovers the confession and grabs it, planning to kill Johnny once the guards are distracted. The escape ends with them trapped in a railroad boxcar surrounded by guards.

Frank sees Johnny's written confession and realizes it exposes him as the real murderer. To protect himself from the truth surfacing, Frank shoots Johnny, hoping to silence him permanently. He places the gun next to Johnny and surrenders, claiming he was unarmed, but Johnny, though dying, manages to tell the guards the truth, implicating Frank and clearing Fred's name.

Even after being shot by Frank and left dying in the railroad boxcar, Johnny uses his last breath to tell the guards the truth. He confesses that he stole Fred's gun and that Frank was the one who shot the pawnshop owner. This posthumous testimony finally clears Fred Burke's name and implicates Frank for both murders.

Pop is a mild-mannered older convict who runs the prison library. He serves as a moral compass for Johnny, privately appealing to his conscience and urging him to tell the truth. When Johnny writes his confession during the jailbreak, he leaves it for Pop to find afterward, trusting the older man to do the right thing with the truth.

The fingerprint evidence comes from the gas station robbery they committed earlier. Investigators match the fingerprints found at the gas station to Frank and Johnny, leading to their arrest and conviction for that crime. This is separate from the pawnshop murder, but it sends both men to Sing Sing, where they end up imprisoned alongside the innocent Fred Burke.

Frank steals the confession because it directly implicates him in the pawnshop murder. The document states that Johnny stole Fred's gun and that Frank did the shooting. If this confession surfaces, Frank faces execution for the murder, so he grabs it and plans to kill Johnny to keep the secret hidden. The confession is the only evidence that could expose Frank's crime.

Madge, Johnny's sister, is engaged to Fred Burke. Even though she doesn't know Johnny was involved in the crime that Frames Fred, she pleads with him to come forward and reveal what he knows. Her desperation to save her innocent fiancé drives her to confront Johnny directly, adding to the emotional pressure that eventually leads Johnny to write his confession.

The prison authorities become suspicious of the uneasy alliance between Frank and Johnny, so they transfer Johnny from the shoe factory to the prison library. This move separates him from Frank's direct influence and puts him under the guidance of Pop, the older convict who runs the library. The change creates space for Johnny's conscience to develop and eventually leads to his decision to confess.

Carey, Fred's lawyer, deduces through investigation that Johnny was the one who took Fred's gun and that Frank was the actual shooter. However, despite his suspicion, Carey lacks solid evidence to prove this in court. Without Johnny's confession or other corroborating proof, Carey cannot secure a stay of execution, leaving him helpless to save Fred until Johnny finally comes forward.
