Ellen Bouché travels to Antwerp to face a terrible truth: Her daughter Sarah lies in the morgue, dead from a fatal drug cocktail of crystal meth and heroin. The stunned mother is assisted by her friend Maggie, whom Ellen knows from her student days in the Belgian port city. A few hours after seeing Sarah's body, Ellen receives an unimaginable text message in the middle of the night: it is an emergency call from her daughter, which arrived two days after the time of death! Ellen refuses to believe the obvious explanation that it is just an unusual delay in transmission. Her maternal instinct immediately kicks in. In fact, something unimaginable seems to be going on, because the student's body has suddenly disappeared and evidence of a connection to a secret voodoo cult is found in her apartment.
