The pressure’s really piling up on Greg Heffley. His mom thinks video games are turning his brain to mush, so she wants her son to put down the controller and explore his “creative side.”
As if that’s not scary enough, Halloween’s just around the corner and the frights are coming at Greg from every angle.
When Greg discovers a bag of gummy worms, it sparks an idea. Can he get his mom off his back by making a movie . . . and will he become rich and famous in the process? Or will doubling down on this plan just double Greg’s troubles?
媽說我是個有想像力的聰明小子，只不過……我得學著用想像力做點正經事……
葛瑞身上的壓力與日俱增。老媽覺得和電動過度親密只會變成腦袋空空的笨蛋，所以希望兒子速速放下電玩搖桿，積極探索他「具有創意的一面」。她甚至異想天開要幫葛瑞找個可以見賢思齊的新朋友。想也知道，不可能嘛！
偏偏這樣還不夠嚇人！隨著萬聖節日漸逼近，各種驚悚的事物開始從四面八方攻向葛瑞……他在家裡意外找到一包蟲蟲軟糖，立刻想到一個絕妙點子──拍電影！
他決定身兼導演和編劇，找來萬年好搭檔榮利當主角，熱鬧開拍！葛瑞能夠藉由拍電影這件事讓老媽別再來煩嗎？說不定這部電影還可以讓他一舉成名、海撈一筆？還是他加倍投注的心血，只會讓他加倍的衰？
