For a three-act plot analysis, put on your screenwriter’s hat. Moviemakers know the formula well: at the end of Act One, the main character is drawn in completely to a conflict. During Act Two, she is farthest away from her goals. At the end of Act Three, the story is resolved.
Act I
Hawkeye, Chingachgook, and Uncas escort two pretty ladeez and their clueless military guide to reunite with their father at Fort William Henry.
Act II
Fort William Henry falls to the French and its occupants are massacred. In the melee, the two women are taken captive by an Indian named Magua.
Act III
Cora, Uncas, and Magua are killed. Chingachgook proclaims himself the last of the Mohicans.
