Sounds like a premium service from an Irish hooker, but it’s far from it! You get 6 teens who call themselves the Flock and they’re a mixture of birds and humans. They escape from the lab they were held captive in (what you thought they came from outer space?) and fly around the place, getting fed stale bread by old people in parks. They also fly / run away from a group of werewolf thingys as well.
