Daybreakers plot
"In 2019, The Most Precious Natural Resource... Is Us."
In 2019, a massive disease has transformed almost the entire world population into vampires. One minus: the supply of humans is limited and due to a drastic blood shortage, the underprivileged among the vampires begin to transform into bat-like monstrosities. It's up to scientist Edward (Ethan Hawke) to fabricate a blood substitute, but when he comes into contact with an underground human group and discovers a possible cure for vampirism, he too becomes a target of his own organization.
