Since their Fin.K.L. days, the women have all pursued successful careers, with three going on to become in-demand actresses, and Lee Hyori becoming one of the most successful Korean female solo singers of all time.
All that changes when the quartet reunites for a cross-country camping trip reality show that sees them travel the length and breadth of South Korea – reminiscing about old times, catching up on each other’s lives, and getting into brand-new adventures.
At the end of their quest, the four women must decide if they will reunite once more – on stage this time – to perform at a concert marking 21 years since their 1998 debut release “Blue Rain.” Will the trip generate enough nostalgia to convince them to perform as Fin.K.L. once more – or will they decide to let go of the past once and for all?
