A while ago, I asked Twitter for suggestions for blog posts, and one of the subjects that came up was the story engine.
As you might imagine, the story engine is the thing that’s pulling your narrative train up the hill, the reason why things are happening in the first place. It can take many forms – a specific goal, a threat to the protagonist or those he loves, a ticking clock. It can be extremely obvious – there’s no doubting what the story engine of Die Hard or Pacific Rim is – or, in a mumblecore or slice of life movie, it can be remarkably nebulous. But in any good story, it’s there, moving events along.
So, particularly if you’re one of those writers who starts off with character first, how do you find a story engine that will keep your narrative on the tracks? (Note to self: enough with the train metaphors!)
The best story engines are derived from the core of who your protagonist is. The story engine for Aliens is ‘stay alive and destroy the alien infestation’. But it arises out of the core of who Ellen Ripley is: a mother who has lost her child. That drives Ripley to protect the orphaned girl Newt, and it’s reflected back at her in the form of the Alien Queen, also a mother trying blindly to protect her offspring. The desire to stay alive, to protect your family (the company, the ‘family’ of marines, Newt) and wipe out whatever threatens it, is a powerful, primal story engine.
Which brings us to another property of the good story engine: it’s a primal desire. The screenwriting teacher Blake Snyder said that the best goals are the ones a caveman would understand. Survival, protecting family and tribe, physical security (money, property, job), love/sex, and the desire for some kind of personal fulfillment or artistic expression – these are the basic needs any human would recognize, and if they drive your story, you’re off to a good start.
For example, the fictional Mark Zuckerberg depicted in The Social Network might be a difficult character for us to empathize with, because his goal in founding Facebook is obscure. So Aaron Sorkin imposes a story engine that we’ll all understand by opening the movie with Zuckerberg being dumped by his girlfriend. That encourages us to filter everything he does through that rejection, to see it as a desire to win her back, or at least convince her she was wrong about him. With sex as our story engine, suddenly the rather dry story of how a smart guy founded a big company becomes primal, and accessible.
And the best story engines are broad enough to be flexible. Your story is going to go through a lot of twists and turns, victories and defeats, and hopefully a few unpredictable surprises. So your story engine needs to be broad enough to encompass changes of short-term goal, and the inevitable, necessary transformations your protagonist will undergo.
Unless we can feel the same story engine pulling us down the tracks, all the way through the narrative, the story will feel fragmented and confusing. The easiest way to avoid this is to ensure you have a smooth transition from want to need to goal to story engine. Take Die Hard: McClane’s ‘want’ is to spend Christmas persuading his wife to give up her job and come back to New York with him. His need is to realise her desires are as important as his. His goal is to save her: and the story engine, the fact that he’s the only person in any position to do so, is a mechanism for him to both realise his goal and move from want to need.
So, get that story engine working for you!
