A botanist arrives in Berlin for a conference and, after a car accident leaves him briefly comatose, wakes to find his identity erased: another man wears his name, his wife looks straight through him, and no record confirms he exists. Aided by a young immigrant taxi driver, he races through the city to reclaim his life while unseen forces try to silence him. Jaume Collet-Serra spins a slick, paranoid European thriller of mistaken identity and buried conspiracy, anchored by white-knuckle chases and a twist that quietly reframes everything that came before.
