Zoe's day starts with a video call from Maggie. Zoe is then torn between treating a six-year-old girl who was run over by her father or a pregnant woman fearing her baby is coming. She prioritises the six-year-old girl; but she dies. Then, on the way home the pregnant woman suffers contractions, causing her ex-boyfriend to be distracted resulting in a car crash. When they return to the hospital, Zoe must choose whether to perform a caesarian or REBOA - she picks the REBOA, however both the mother and baby die. However Zoe then wonders what the outcome would be if she retook her day. Zoe retakes her day, this time prioritising the pregnant woman. The six-year-old girl dies. On the way home the pregnant woman is again involved in a car crash and is admitted again; however this time she performs a caesarian. The baby survives but the mother dies. Zoe then gets up half an hour earlier: this time everything goes right - the six-year-old survives, and so does the mother and baby. (thetvdb.com)
