片名《Tubelight》的意思来自影片中的一段台词: “信心就像是一盏日光灯, 点亮它需要花一些时间。 但一旦当它点亮, 它会照亮周围的一切。”In a small picturesque town in North India, Laxman (Salman Khan) lives with his younger brother Bharat (Sohail Khan). The two have no other family and are inseparable. Laxman's world comes crashing down, when war breaks out and Bharat gets drafted into the Army. A helpless Bharat leaves a devastated Laxman behind. News from the border only worsens, as the tension continues to escalate. Seeing the carnage around him and worried for his brother, Laxman decides he must stop this conflict and get his brother back.
