There's something terrifying about the idea of a mysterious plague or epidemic that causes people to turn into monsters that people love tuning in to watch. Just look at The Walking Dead franchise for proof, or 2018's Bird Box. Sandra Bullock's 2018 Netflix movie blew fans away with an unseen threat that unleashed pure mayhem, leading people to walk around with blindfolds in order to survive. Bird Box Barcelona continues that story, only this time the action is set in Spain.
In Bird Box Barcelona, a father will do whatever it takes to keep his daughter safe from an unseen threat that no one understands. Without being able to see it, all they can hope to do is to flee from it.
