What Happens in Baby Face Nelson: Full Plot Summary

The whole story of Baby Face Nelson (1957) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Chicago mob boss Rocca engineers the release of Lester M. "Baby Face Nelson" Gillis [Mickey Rooney] from Joliet, hoping to hire him to kill a labor organizer. Gillis refuses, preferring to work with Rocca's gang on robberies instead. He meets mob moll Sue Nelson [Carolyn Jones], and the pair quickly spark a relationship. When police burst into his hotel room, they uncover a gun Rocca planted to frame Gillis for the labor leader's murder. Gillis swears revenge, escapes with Sue's help, and then guns down Rocca and two henchmen, adopting Sue's surname as an alias.

In a pharmacy holdup, Gillis is wounded by a gunshot. He seeks help from Doc Saunders [Cedric Hardwicke], whose patients include America’s most wanted criminal, John Dillinger [Leo Gordon]. With a new nickname—Baby Face Nelson—he joins up with Dillinger and soon becomes the FBI's second-most wanted man.

The rampage continues as the ruthless Baby Face Nelson goes on a killing spree, including innocent motorists to steal cars. He chafes at not being the top dog beside Dillinger, but after the arch-criminal is shot in Chicago, the mantle passes to him. He commits multiple murders, even killing Doc in a fit of anger, and he frightens Sue by leveling a rifle sight at children.

Cornered by a roadblock, Baby Face Nelson flees on foot and is wounded several times. He staggers into a graveyard, briefly pleads with Sue, then taunts her, and she ends his misery.

Baby Face Nelson Plot Explained: Your Questions Answered

The questions people ask most about Baby Face Nelson (1957): what happens in the confusing scenes, why the characters do what they do, the twists, hidden details and what the ending means. Each answer contains spoilers.

Q1

Why did mob boss Rocca arrange for Gillis's release from jail?

Rocca engineered Gillis's release from Joliet prison specifically to hire him as a hitman to kill a labor organizer. However, Gillis refused this assignment, preferring instead to work with Rocca's gang on robberies. This refusal set Gillis on his own criminal path rather than becoming Rocca's personal assassin.

Q2

Why did Gillis refuse to kill the labor organizer?

The exact motivation for refusing isn't explicitly stated, but Gillis clearly preferred the more profitable and less politically charged life of a robber alongside Rocca's gang. He was willing to commit crimes for money but drew a line at what appears to be a targeted political assassination, showing he had some boundaries despite his violent nature.

  • labor organizer
  • refusal
  • murder

Q3

How did police find Gillis in his hotel room with a planted gun?

Why did Gillis adopt Sue's surname as his alias?

After killing Rocca and his henchmen, Gillis chose to take Sue's surname 'Nelson' as his alias. This was both a way to honor his partner who helped him escape the police raid and revenge his ambush, and it gave him a new identity as he embarked on his criminal rampage.

Q8

Why did Sue kill Nelson in the graveyard?

Wounded and cornered by police, Nelson staggered into a graveyard where he pleaded with Sue to end his suffering. He then taunted her, daring her to pull the trigger. Sue finally shot him, granting his request for a mercy killing rather than letting him be captured or die slowly from his wounds.
