主角Benji是一個充滿夢想的男孩，就算一般人不相信的事情，他也深信不疑。
他尤其堅信水怪的存在……
當Benji發現叔叔的生意陷入困境時，他有一個計劃：他要證明洛奇湖有水怪，藉此吸引大量遊客湧入。但Benji可能因此要面對一些意想不到的怪物……
Benji McLaughlin is a visionary. He believes in things other people think are impossible, like that he and his brother Stanley will be happy living with their uncle, and that the Loch Lochy monster is real, and that his parents will come home safely one day.
So when he finds out that Uncle Hamish's holiday business is struggling, Benji's not worried. He has a visionary plan. Together with his new friends, Murdy and Mr Dog, he sets off to prove that the Loch Lochy monster exists, and bring tourists flooding in.
But Benji might have to confront different monsters to the one he expects.
