He is a member of a group of trappers and hunters hunting for pelts in the unsettled wilderness in 1823. Their group is attacked by Arikara Indians, with many casualties.

 

  During the retreat, he saves the life of the young Jim Bridger who is almost drowned by an Arikara. Fitzgerald and a handful of trappers escape by raft, though their leader Henry expects that they are still pursued by the Arikara. Despite Fitzgerald's urge to stay on the river, The group continues the journey inland as advised by experienced hunter Hugh Glass. After the people got on the shore, Fitzgerald continuously expresses his discontent with the current situation. He then tries to provoke Glass, referring to the Indian heritage of his son. However, Fitzgerald is ordered to stand down by Henry.

 

  When Glass is severely injured after having been mauled by a grizzly bear while hunting for food, he is found by his group soon after. While most worry and try to save Glass, Fitzgerald instead remarks that he shouldn't have shot at the bear as now the forest is crawling with bears who got drawn to the place by the noise. Fitzgerald is almost beaten by the other trappers and leaves the others to tend to Glass's wounds. Talking to the men who share his concerns, Fitzgerald states that the proper thing to do would be putting Glass out of his misery.

 

  While the trappers make camp, the leader of the Arikara meets with french trappers, with whom his tribe frequently trades. He demands and gets horses to pursue his hunt, telling the french that they are following Glass's group because the white men stole his daughter.

 

  With Glass too weak to walk, the trappers are forced to carry him on a makeshift litter. When they have to cross a mountain, they are unable to lift Glass. There, Fitzgerald finally persuades Henry into mercy-killing Glass. However, Henry is unable to kill him and instead offers a reward out of the company's coffers to the two men who will remain behind with Glass to see it through. Glass' son volunteers, as do Jim and Fitzgerald, who claims that as his pelts were lost, he has to find a way to make up for the lost money. Before leaving, Henry tells Fitzgerald to take good care of Henry and to give him a proper burial when time, as Glass has earned it. Fitzgerald promises it and the trapper group leave, leaving Fitzgerald behind with Glass and his son.
