一群钓鱼专家与一位知名的鲨鱼科学家携手合作，用一艘特别的船舶、全世界最大的鱼钩和一个史无前例的计划来捕获大白鲨。然后为其做检查，采集它们的血液样本，并植入先进的追踪装置，通过这些去揭开世上最大掠食鱼类的神秘面纱。

每年有上千万只鲨鱼被捕杀，它们的数量在急剧下降，研究鲨鱼的迁徙路径和需要对保护鲨鱼来说很关键。几位鲨鱼冒险家乘船驾艇在海上捕捉鲨鱼，以在鲨鱼身上植入标签，进行卫星追踪和研究。经过艰苦的努力，他们战果颇丰，为鼬鲨、双髻鲨、白边真鲨等好多种鲨鱼安上了标签。

不管是在公海、沙滩，还是远洋轮渡之上，饥饿的鬣狗心里只有一个想法：将美人鱼Marina变成自己的美食。在天才寄居蟹伯尼的协助下，它想出了一个最为疯狂的猎捕计划……然而，它显然忘了鲨鱼哥的存在——这条浑身肌肉的大鲨鱼会竭尽全力保护他心爱的美人鱼！

一半是鲨鱼，一半是小狗，拥有一颗宽广的心，并且肚子里装满了鱼条！鲨鱼狗和他的人类朋友迈克斯将踏上各种愚蠢和混乱的冒险。

影片改编自经典童话书，讲述一位四岁男孩使用具有魔力的紫色蜡笔，通过绘画自由创造身边的世界，展开一段充满奇幻与冒险的旅程。

Stuck in the wilderness for five years on a quest that he never asked for, comedically inept wizard Perf (Christian Doyle) finally has a chance to sleep in a real bed. In a real town. In something approximating civilization. But first, he'll have to evade his keen-eared companion, the elf Nara (Alyssa Kay), who is driven to achieve her destiny at any costs. Meanwhile, the Pale Lady (Paige Barnett) weaves a web of doom around our heroes in pursuit of her plans for the undead priest Carrow (Brain Lewis), Rilk (Jesse Lee Keeter) and his orcs pursue the psychotic orcslayer Glorion (Kevin Pitman), and two competing bards (Fran Kranz and Emilie Rommel Shimkus) battle for ownership of the world's most important epic. The journey... that is, the quest... the JourneyQuest continues in this third season of the acclaimed fantasy comedy series, presented here as an uninterrupted feature film.
