The script
Every line as it is spoken in the film, in order.
Now pull back. From one synapse, to your brain, to your body. To everyone you have ever met. To the planet.
Everything with a backbone carries this lock. A fly has none at all.
Justin, on camera
You have been making your own medicine since before you were born. The plant just showed us where to look.
