What’s the story of ‘Not Alone’?

The movie will see Chalamet voicing Joe, an introverted rocket mechanic who lives a quiet life alone. Gomez is set to play Fran, a brilliant astro-botanist who is developing the world’s first-ever plant-fueled rocket.

And the official logline reads:

“When Joe and Fran are brought together to prepare for the inaugural launch of this revolutionary rocket, there are immediate sparks, but neither is particularly adept at romance. Life becomes more complicated when three aliens — tiny, unruly and adorable — take refuge in Joe’s home. Dunk, Welly and Shirm are on the interplanetary run from a zealous-yet-inept officer of the law named Zandro. The aliens determine that Fran’s rocket could provide their means of getting back home to safety.”
