该剧改编自真实事件。1988年12月21日，伦敦飞往纽约的泛美航空103号班机遭遇恐怖袭击，造成259名乘客和机组人员丧生，另有11名洛克比当地居民死亡。Jim Swire博士（科林·费尔斯 Colin Firth 饰）的女儿也在洛克比空难中遇难，他被提名为英国受害者家属的发言人，竭尽全力调查空难真相。
The plot of the movie revolves around a U.S. Marshal, on a snowy Christmas Eve, who seeks refuge from her judgmental family by immersing herself in work. However, her plans take an unexpected turn when she gets snowed in with an unlikely companion – a cheerful and heavily pregnant fugitive. To complicate matters, she finds herself tasked with keeping this soon-to-be mom safe from both labor pains and a merry band of bumbling goons led by a trio of hitmen who couldn’t find a reindeer in the North Pole.
