Back in Scotland 1874, Jack is born in the coldest day . On account of the extreme cold, his heart stops beating. The mid wife at Edinburgh finds a way by replacing his spirit with a 18, to rescue him. He resides and remains under the midwife maintenance. But he shouldn't become mad or excited by causing his clock to stop 20, as that threatens his entire life. Worse than that, when he grows up, he has to manage the fact he can't fall in love as his heart too will discontinue.
