The father and son get into disputes daily and his elder brother Ma Keung and his wife Lo Lai Seung are often stuck in between and have to settle the disputes. The couple also holds the heavy responsibility of raising their kids. Three generations in the Ma family all live together and encounter different situations, experiences, and system of values.
