The plot of A.R. Murugadoss' Ghajini borrows heavily from Christopher Nolan's Memento. Sanjay (Aamir Khan) suffers from short-term memory loss. He spends his days attempting to take revenge on those responsible for the death of his girlfriend, but his condition complicates this process. To help him, he constantly makes notes for himself. Some of the notes take the form of crude homemade tattoos.
