The Black Island: Part 1 - S1-E10
Continuity mistake: Mueller's assistant gets hit on the head with a bag of counterfeit bank notes. Mueller then walks over to the assistant and ends up stepping on a rake, smacking himself in the face with it. In the wide shot that shows Mueller walking over to the assistant, we can notice the direction between Mueller and the rake would have had Mueller step on the edge of the rake. As it cuts to the close-up of Mueller's foot stepping on the rake, he is now shown stepping on the middle of the rake. (00:20:35)
