Threshold is a 50-minute film composed of six short stories produced between 2015 to 2020 in Hong Kong, each capturing a human life on the verge of transformation or collapse. From a police officer’s devastating choice in the mountains (One Bullet 2018), to a man confronting his fractured self while held captive (Hostage 2018), to a fragile romance between a blind woman and a heart-stricken lover (Invisible 2015), the anthology explores love, sacrifice, and identity under impossible pressure. A pair of students struggle for freedom amid social unrest (Off Track 2020), a man given one last day by God seeks to complete what truly matters (Final Call 2018), and a brief but startling twist (Ramp 2018) closes the collection. Bound together by the moment we cross from what was to what will be, Threshold reveals that at every breaking point lies a choice that defines us.

《臨界點》是一部50分鐘的電影，由六個於2015至2020年期間在香港製作的短篇故事組成，每一個都捕捉到人生處於轉變或崩潰邊緣的瞬間。從一名警察在山中面臨毀滅性的抉擇（〈一顆子彈 2018〉），到一名男子在被囚禁中直面破碎的自我（〈人質 2018〉），再到一段盲女與心臟病纏身男子的脆弱愛情（〈愛。不見 2015〉），本片探討了愛、犧牲與身份在極端壓力下的意義。兩名大學生在社會動盪中掙扎求生（〈迷途 2020〉），一名男子在上帝給予的最後一天裡尋求完成最重要的心願（〈最後的呼喚〉），以及一個短暫卻震撼的反轉（〈斜坡 2018〉）為整個合集劃上句點。這些故事由一個共同的瞬間聯繫在一起——跨越從「曾經」到「將來」的臨界點。《臨界點》揭示了：在每一次崩潰邊緣，都存在一個定義我們的選擇。
