Miguel Hermoso's Like Lightning offers a fresh take on a familiar scenario, the teenaged boy searching for his unknown father. Pablo is a typical teen, with a fondness for football and sneaking beers with his buddies. He enjoys a comfortable upper-middle class life with his mother (Assumpta Serna), a successful lawyer and former feminist rabble-rouser, but has a gaping hole at the core of his identity: he has no idea who his father is. Preoccupied with the question to the point of obsession, he sets out in search of answers, and finds himself on a trail that leads to the Canary Islands.
