The film also explores the theme of duality, with Oscar and his brother Judas representing two sides of the same coin. The film's use of symbolism is also noteworthy, with recurring motifs such as the use of butterflies, flowers, and water to represent transformation and transcendence.

"Enter the Void" was a polarizing film at the 2009 Cannes Film Festival, with some critics praising its innovative style and themes, while others found it excessive and self-indulgent.

As Oscar navigates the afterlife, the film flashes back to his life on earth, revealing his relationships with his brother, his girlfriend, and his friends. Through these flashbacks, the film explores themes of mortality, spirituality, and the meaning of life.

The film tells the story of Oscar (played by Romain Levi) and his twin brother, Judas (played by Gilbert Melki), who are involved in the Tokyo club scene. One night, Oscar is shot and killed by a bouncer outside a nightclub. The film then follows Oscar's spirit as he enters the afterlife, where he encounters various surreal and often disturbing visions.
