Berlin Syndrome (2017)

While holidaying in Berlin, Australian photojournalist Clare meets Andi, a charismatic local man, and there is an instant attraction between them. A night of passion ensues. But what initially appears to be the start of a romance suddenly takes an unexpected and sinister turn when Clare wakes the following morning to discover Andi has left for work and locked her in his apartment. An easy mistake to make, of course, except Andi has no intention of letting her go again. Ever.
