Based on the absurd but true 1973 bank heist and hostage crisis in Stockholm that was documented in the New Yorker as the origins of the 'Stockholm Syndrome'.
Lars Nystrom (Ethan Hawke) dons a disguise to raid a central Stockholm bank, then takes hostages in order to spring his pal Gunnar (Mark Strong) from prison. Negotiations hit a wall, and as hours turn into days, Lars alternates between threatening the hostages and making them feel comfortable and secure.
The hostages develop an uneasy relationship with their captor, which is particularly complex for one of the hostages Bianca (Noomi Rapace), who develops a strong bond with Lars as she witnesses his caring nature.
This connection gave rise to the psychological phenomenon known as "Stockholm syndrome". A light touch and well-chosen cast keep this film consistently entertaining.
