Reality Check (Chinese: 心路GPS) is a Hong Kong television drama serial created by Lee Yim-fong and produced by TVB. It first premiered on Jade in Hong Kong on 18 February 2013, airing to 20 episodes with two episodes back-to-back.
The serial centers on the relationships between Summer (Ruco Chan) and his two mothers - his foster mother, Tsui (Louise Lee) and his estranged birth mother, Han (Rebecca Chan).
In preparation for filming a brand-new reality show, senior TV producer Summer Ha (Ruco Chan) is ready to document a Hong Kong teenager Sky Cheung (Hero Yuen), who goes back to mainland China from the city in pursuit of the realm of returning to nature through his experience of the rural life there.
However, the TV station has a drastic shortage of manpower, so Summer recruits a rookie May Hui (Priscilla Wong) as his assistant, and his best friend Leung Chung-shun (Mak Cheung-ching) as the photographer. During the filming, each of them witnesses the significant change of the hero’s personality when this typical Hong Kong Kid is confronted with the culture conflicts in the countryside. In addition, everyone’s blind spot in daily life has also been addressed. Summer, who is always subjective and persistent, starts afresh to review the love-hate relationship between him and his foster mother Lau Tsui-wan (Louise Lee) as well as his biological mother Ha Siu-han (Rebecca Chan). Being diligent and sincere, May works so hard to recover her self-esteem and the long-lost paternal love. Male chauvinist Shun's quarrel with his family members over trifles stirs up a great disturbance, resulting in his family being torn to pieces. Will the GPS Guide for the Soul eventually help them out of their predicament?
