The Ordinary World
The hero’s background and personal history is established, and often the hero is suffering from some sort of malaise, or need to escape their own routine. A perfect example of this is the opening scene of The Wizard of Oz.
The Call to Adventure
The hero’s situation changes, and they are unexpectedly presented with a task that will shake up their world permanently. Think Clarice Starling being assigned to interview Hannibal Lecter by Special Agent Jack Crawford at the beginning of The Silence of the Lambs.
Refusal of the Call
The hero fears the unknown consequences of embarking on the adventure and hesitates, often out of some sort of obligation or uncertainty, like when Luke Skywalker initially balks at joining Obi-Wan Kenobi in his mission to save Alderaan in Star Wars.
Meeting with the Mentor
The hero meets a wiser, more seasoned traveler who will impart knowledge, training, or special items that will assist them on their journey, and help the hero find their inner courage. This is what happens, for example, when Freddie Quell meets Lancaster Dodd for the first time in The Master.
Crossing the Threshold to the Special World
The hero finally leaves their ordinary world, and ventures to an unfamiliar place, embodied perfectly by the moment when Neo takes the red pill in The Matrix.
Tests, Allies and Enemies
The hero endures a series of tests, and figures out who in this new world can and cannot be trusted. This is practically every scene in the Kill Bill films.
Approach to the Inmost Cave
The hero, having figured out the rules and alliances of the new world, prepares for the ultimate test of their character. Think of when Ripley dons the mech suit to fight the queen in Aliens.
The hero, upon entering a central space in the new world, is forced to face their greatest fear, or confront their own mortality, like when Indiana Jones must brave the snake-infested Well of the Souls to retrieve the ark of the covenant in Raiders of the Lost Ark.
The hero accomplishes their goal, but an uneasiness remains due to the sacrifices it took to get there, or there is danger of their work being undone, such as when Simba finally ascends to the throne at the end of The Lion King.
The Road Back
The hero leaves the new world and ensures that their mission was not in vain. This is often presented in the form of a chase scene, with the perfect example being the climactic bike race to the forest in E.T. The Extra-Terrestrial.
The hero is severely tested one more time upon returning home, and is often subjected to an ultimate sacrifice, or a moment of clarity. Think when Jules Winfield atones for his sins by defusing the robbery at the coffee shop in Pulp Fiction.
Return With the Elixir
The hero either returns home permanently or continues their journey, having gained some sort of valuable knowlege that could make the world a better place, like when Therese realizes she can allow herself to be happy and returns to Cate Blanchett’s titular character in the final moment of Carol.
