Wild Sing

In 2001, nineteen-year-old dancer Hwang Hyun-woo is discovered by small-time producer Park Yong-gu and recruited into a new co-ed pop group called Triangle. Alongside rapper Gu Sang-gu and vocalist Byeon Do-mi, he trains for a year before debuting with the hit song "Love Is". The group quickly becomes a sensation, topping charts and building a devoted fanbase. Their success continues with a second album, and they appear destined to become one of the biggest acts of their generation.

At the height of their fame, however, everything collapses overnight. During a celebration party, rival singer Choi Seong-gon is unknowingly drawn into a drug scandal that destroys his career. At the same time, Triangle discovers they have never received proper payment for their work. Soon afterward, news breaks that their hit song was plagiarized, despite being publicly credited to Hyun-woo. Before the group can respond, producer Yong-gu flees the country, abandoning them and leaving them to face the backlash alone. As tensions rise, Do-mi decides to leave, and Triangle disbands in disgrace.

More than twenty years later, Hyun-woo is a forgotten celebrity surviving on minor radio and television appearances. After being dismissed from yet another program, he receives an unexpected opportunity: Triangle is invited to reunite for a major concert, and a successful performance could lead to a new television music show. Determined to seize what may be his last chance, Hyun-woo sets out to reunite the estranged members despite their unresolved conflicts.

He finds Sang-gu struggling with debt after failed solo ventures and working as an insurance salesman. Do-mi, meanwhile, lives comfortably as the wife of a wealthy businessman but feels trapped in a dull life dominated by family expectations. Though both initially resist, Hyun-woo gradually convinces them to return. At the same time, former star Choi Seong-gon, whose career was ruined by the scandal decades earlier, is also invited to perform at the concert, hoping for a comeback of his own.

As the reunion approaches, old wounds resurface. The group unexpectedly encounters Yong-gu, who has secretly returned to South Korea under a new identity after years abroad. Furious over his betrayal, the former members chase him through a series of increasingly absurd accidents and misunderstandings. Their pursuit spirals into a chaotic road trip involving traffic police, car crashes, failed rehearsals, and Seong-gon's own personal struggles. Meanwhile, they risk missing the concert entirely.

After countless setbacks, the group finally reaches the venue at the last possible moment. Exhausted and with everything seemingly working against them, Triangle takes the stage. Ignoring instructions to perform the songs exactly as before, they reinvent the performance: Sang-gu adds new rap verses inspired by his life, Do-mi showcases her vocal talent, and Hyun-woo unleashes the breakdancing skills that first made him famous. The audience responds with overwhelming enthusiasm, proving that their music and bond still resonate after all these years.

The concert becomes a triumphant second chance for all of them. Although Do-mi ultimately chooses to return to her family life, she remains connected to the group in a new role. Some time later, Hyun-woo and Sang-gu continue performing as a revamped version of Triangle, with Seong-gon joining as the new vocalist. Backed by Do-mi as their producer, the group embarks on a new chapter, finally finding the recognition, closure, and friendship they lost decades earlier.
