Three young women's week at the beach turns into a transhumanist mystery romp in one Estonian summer.

While spending the summer together at a beach house, Grete, Sarah and Mia meet a guy who calls himself Dr. Mindfulness and sells his own meditation app. Although Dr. Mindfulness speaks and performs like a complete charlatan, his app and devices surprisingly deliver a mind-bending experience as promised.

Detectives Jack and Katrin (Interpol) arrive on the scene to confirm that Dr. Mindfulness is a fraud and bigger, darker forces are behind the app. The app is somehow related to the operating system of the Tallinn Zoo, and strange changes in the body chemistry of its users start to turn them into something between pollen and cosmic dust. Grete and Sarah have succumbed and are on the loose as Mia has slipped the detective's grasp.

The detectives race desperately to solve the case, not knowing whether they are trying to stop a cybercrime or prevent a large-scale biological weapons attack. Mia searches for Grete and Sarah to see what has become of her old friend, only to grapple with the choice to save them (from what) or join them (for what). It’s been a long summer and it may just go on forever.
