Plot

Aparichithan narrates the story of three carefree college friends - Meenu, Simi and Devi, known as "Three Roses" – who keep landing in trouble. After one such incident where Devi, the leader of the trio, is caught red-handed trying to steal question papers on the eve of exams, they go underground to avoid facing their peers and families. With the help of Chacko, Simi's fiancée, they arrange accommodation with a woman psychiatrist who is also an expert in "tantrik" mysticism and Ouija board, in an isolated house. Fresh trouble begins there, leading to the landlady chasing the girls out, saying a wandering soul is following them.
