Parque Lenin is the name of the amusement park located in La Habana, Cuba, where the Kessel brothers share their last remaining memory together; one shared event divided into three incompatible visions: the ideal day, a farewell and betrayal.—Anonymous

Four years ago, Antoin, Yesuan and Karla lost their mother. Nowadays, Yesuan overcomes his mourning through the illusion that Antoin, his oldest brother, will come back to Cuba. Antoin lives in France where he tries to build a career as an opera singer. Meanwhile, Yesuan tries to replace the role of their parents and takes care of his younger sister who is going through her sexual awakening. Parque Lenin is the theme park where the three siblings share their last memory together.
