Om Shanti Om
The next moment, Om is shocked when Pappu and Anwar reach the scene along with "Sandy". As he glances back at the one in front of him, he realizes that the one who had revealed the proof of Shanti's murder and killed Mukesh was the real Shanti, a.k.a. the ghost of Shanti. She was responsible for lighting the photograph with fire and knocking Mukesh unconscious too, helping him in his plan. Om reunites with Sandy and waves at Shanti who tearfully smiles at him and disappears, having finally attained peace.
