Ethan hides as a humble painting restorer in Amsterdam for ten years, plotting revenge for his master’s framed death by art tycoon Morel and his criminal chain. Using the secret alias Ghost Painter, Ethan sets traps to expose greedy gallery owner Van der Meer, plagiaristic appraiser Dirk, corrupt auction boss Hector and crooked museum director Viola one by one. He gathers solid evidence of fake authentication, cultural relic smuggling and murder. Finally, Ethan infiltrates Morel’s private castle, unveils all hidden crimes in a live broadcast, clears his late master’s name and recovers the priceless broken masterpiece The Night Watch Fragment. Abandoning his vengeful ghost identity, Ethan becomes an official national museum chief restorer to protect art for ordinary people.
