A man returns to his job in a company that transports animals. On his first trip, one of the cages doesn't seem to be carrying what it should. The mystery lurking in his truck pushes him to the limit of his own sanity.

Everyone is locked up, but Clementina and the man she's quarantined with won't stop working. We know little about him, and even less about her: we just see over and over again her mysterious face, which seems to defy everything.
