Piku is a delightful film about very little and yet it says so much. Nothing much happens in Piku. We are introduced to the main characters – Piku, an architect, who lives with her father in Delhi. Deepika Padukone plays her. Piku is fierce – both in her attitude toward life and in her love for her father, Bhashkor Banerjee. Bhashkor, played by Amitabh Bachchan, is, as Sweety in Kaminey would say, a single-piece. He’s 70. He’s a hypochondriac – so he’s almost disappointed when his blood pressure is normal. But the central motif of his life is bowel movements.
