"Snapshot," also known as "One More Minute" in some regions, is a psychological thriller released in 1979, directed by Simon Wincer. The film follows the story of Angela (played by Sigrid Thornton), a young woman who becomes entangled in a web of deceit and danger after she agrees to participate in a modeling shoot.

Angela, a shy and reserved supermarket employee, sees the modeling opportunity as a chance to break free from her mundane life and pursue her dreams of glamour and excitement. However, her initial excitement soon turns to fear and suspicion when she realizes that the photographer, Linsey (played by Chantal Contouri), has sinister intentions.

As Angela poses for Linsey's camera, she becomes increasingly uncomfortable with the suggestive and invasive nature of the photoshoot. Her discomfort escalates when she discovers that the images are being used for a blackmail scheme orchestrated by Linsey and her wealthy lover, Daryl (played by Robert Bruning).

Caught in a dangerous game of manipulation and betrayal, Angela must rely on her wits and resourcefulness to outsmart her adversaries and reclaim control of her life. Along the way, she forms an unlikely alliance with Jack (played by Hugh Keays-Byrne), a sympathetic stranger who offers her support and guidance in her time of need.

"Snapshot" is celebrated for its suspenseful atmosphere, gripping storyline, and standout performances, particularly by Sigrid Thornton in the lead role. The film's exploration of themes such as identity, power dynamics, and the dark side of the modeling industry resonates with audiences, making it a compelling and thought-provoking thriller.
