在这部菜鸟剧情片中,菜鸟叶明贤才挂起警徽，经手第一件案子就走索道德和规范之上，简单案子从来不简单，黑道白道都来参一脚，上有压力，下有阻力，就是自己人才扯后腿。最需要帮手时，又和学长明哥来犯冲，一个猛加速，一个是老油条，最是冤家才聚头。面对警界潜规则，跌滚带爬，震盪早妥协了相安无事的善恶水平面，要让是非都澄清，正义不能等。欢快中带刺，速度感结合爆破力，绝妙戏剧节奏，郑文堂以《菜鸟》针砭社会乱象，官商勾结、毒品交易、帮派入侵校园、贫富差距下种种威逼与妥协。当善恶分界逐渐模糊，站在人性十字路口上，坚持有多难能可贵？宥胜与庄凯勋镜头前以反差对戏，张力十足。只有菜鸟，才能仰望整片天空。
Soon after a young police officer reports for duty, he is confronted with the unspoken rules. There are people who cannot be questioned and cases that cannot be further investigated. Although he has been sidelined, he refuses to give up the old case. However, having spent so much time and effort, will he find out the truth or some long forgotten conscience?
「菜鸟」：老鸟郑文堂的世界首映。台湾小打小闹版的《洛城机密》。我所希望的不只是熱血。
