'See that patch of blue sky' he said. 'Whenever you see one that's where I'll be - thinking of you.' Against the chaotic backdrop of World War II Grace Murphy is working as a midwife in Doncaster Royal Infirmary with her two friends Clodagh and Patsy. In between delivering babies and tending wounded airmen the girls endure bombing raids rationing and the hardships and heartbreak that war brings. But in the faces of the new babies she welcomes to the world Grace always looks for hope as she dreams of a time when the war will end. When the midwives get the chance to go to a dance at the nearby RAF Finningly they jump at the offer. The hangar is crowded with happy dancing couples but when the glamourous Spitfire pilots saunter in looking dashing in their leather flying jackets and brightly coloured silk scarves Grace can't resist taking a peek. And the moment Grace meets pilot Richard Carmichael she knows he will capture her heart. With every daring flying raid Grace and Richard risk losing each other forever. All Grace can do is look out for Richard in the patches of blue sky and hope that fate will bring them their very own wartime happy-ever-after. . .
