A committed dancer struggles to maintain her sanity after winning the lead role in a production of Tchaikovsky's Swan Lake in the Black Swan DVD.

Black Swan is a psychological thriller released in 2010 that delves into the dark and intense world of professional ballet. Directed by Darren Aronofsky, the film follows the story of Nina (played by Natalie Portman), a talented but fragile ballet dancer who is vying for the lead role in a production of "Swan Lake".

Nina is a dedicated and disciplined ballerina who has devoted her life to her craft, aiming for perfection in every performance. When she is cast as the lead role of the White Swan in "Swan Lake", she sees it as the opportunity of a lifetime. However, as Nina begins to prepare for the role, she finds herself descending into a dark and surreal world of paranoia, obsession, and self-doubt.

As Nina immerses herself in the role of the White Swan, she is haunted by the dual nature of the character, which requires her to portray both the innocent and delicate White Swan, as well as the seductive and menacing Black Swan. Nina's pursuit of perfection becomes increasingly obsessive, and she struggles with her own sanity as she becomes entwined in a web of hallucinations, paranoia, and blurred lines between reality and fantasy.

As Nina's mental state deteriorates, she faces challenges from various sources, including the artistic director Thomas (played by Vincent Cassel), who pushes her to embrace her darker side, and the rival dancer Lily (played by Mila Kunis), who seems to embody the characteristics of the Black Swan effortlessly. Nina's relationships with her overbearing mother Erica (played by Barbara Hershey) and her supportive but enigmatic mentor Beth (played by Winona Ryder) also add to the complexity of her psychological state.

As Nina's obsession with perfection and her pursuit of the role of the Black Swan reaches a fever pitch, the line between reality and delusion becomes increasingly blurred. The film builds towards a dramatic and visually stunning climax as Nina's transformation into the Black Swan becomes complete, with haunting consequences...
