Taipei, late Dec 2012. The city is going through an unprecedented winter heatwave, with temperatures in the 30s. Eight-year-old Tiger (Antoine) lives with his divorced mother, Cao Yi (Vivian Hsu), 36, who is struggling to make ends meet with her job as a magazine editor and reduced alimony payments from her ex-husband (Tang Kuo-chung). Tiger, who has a hyper-active imagination and sees his mother as a run-down robot who needs a new model, is not very bright at school and worries his art teacher (Mini Yang) with the dark pictures he draws in class.
