When death is that close, will your heart skip a beat? Two patients are admitted to room no. 509. One is a brilliant nineteen-year-old medical student, suffering from an incurable, fatal disease. She counts every extra breath as a blessing. The other is a twenty-five-year-old drug addict whose organs are slowly giving up. He can't wait to get rid of his body. To him, the sooner the better. Two reputed doctors, fighting their own demons from the past, are trying everything to keep these two patients alive, even putting their medical licences at risk.
