On the day Terry turns 17, he unwittingly gets involved in the kidnapping of a teenager and ends up being sent to an adult prison in Australia. Meanwhile, SU Chen-wei, Terry’s father, is busy filming a movie on the tiny islet of Penghu. He learns about his son’s imprisonment from his estranged wife. He starts to navigate the challenges of traveling between the islet and foreign lands while juggling his filmmaking and legal proceedings.
His son is barely recognizable when Terry appears in oversized, ill-fitting prison clothes before SU. They haven’t seen each other in two years. During the legal process, SU moves into his son’s sublet house. He meets Grace, a Korean girl who unexpectedly lost her life partner. Stranded together in a foreign land, they find themselves isolated in that enclosed house. An ambiguous affection secretly develops between them – their bond oscillates between that of a father and daughter, friends, and even lovers.
Su’s rationality collapses as spectacular fireworks bloom in the sky above Sydney. He drives his son and embarks on a journey of madness, intending to illegally smuggle him out of the country, leaving behind the mistaken ‘heaven’ they once believed in.
