At an international school in Jakarta, a philosophy teacher challenges his class of twenty graduating seniors to choose which ten of them would take shelter underground and reboot the human race in the event of a nuclear apocalypse.

Newly wealthy and disillusioned, Randall, a mobile game developer, asks his old friend Sarah out for dinner to tell her how he actually feels about her. She deflects the conversation, insisting a solution to his crisis of meaning could be to join the dating applications. Heartbroken, Randall follows Sarah’s advice, but this casual and dishonest way of life begins to have dehumanising effects on his mind and body. Without Sarah, however, Randall can’t find it in himself to stop, as he doubles down on the descent into ratty madness.
