Sofia McKendrick is a blind pianist living at an apartment in London, traumatised by her family's murder by Serbian paramilitaries.

During a discussion in an elevator, Veronique discreetly slips Sofia a USB drive and tells her that the perfume is "Liquid Gold".

It is revealed that Sofia has her own vendetta towards Radic, conspiring with her adopted father Niall, a soldier who rescued her as a child.

Sofia hands Nial the drive, with "Liquid Gold" being the password, uncovering Radic's assets and operations.

Meanwhile, Mills watches surveillance of Sofia's visit earlier in the front office, noticing she is looking at something.

Marc encourages her to run, while he takes the fall for Radic's death, and Sofia flees the apartment before the police arrive.

Sofia is depicted as living in Maida Vale, London, where scenes were shot for the film, including a flower shop on Lauderdale Road which was converted to act as a café.

Other filming locations included Brompton Cemetery, Ealing Hospital, the Thames Embankment, New Zealand House and the National Gallery.

Nakedness is a good equaliser and the shower scene also shows the tattoos on my character's body and makes it clear she is not quite who you think.
