Cosmos is a ominous and manic exploration of desire. Witold, who has just failed the bar, and his companion Fuchs, who has recently quit his fashion job, are staying at a guesthouse run by the intermittently paralytic Madame Woytis. Upon discovering a sparrow hanged in the woods near the house, Witold's reality mutates into a whirlwind of tension, histrionics, foreboding omens, and surrealistic logic as he becomes obsessed with Madame Woytis's daughter Lena, newly married to Lucien.
