Dishonored Walkthrough: Abducting Sokolov on Kaldwin's Bridge Nonlethal and Undetected

This video shows the entire mission on Kaldwin's Bridge in Dishonored. In it you deactivate the checkpoint spotlights so Samuel can move the boat closer to Sokolov's Home and then abduct Sokolov from his home and bring him to Samuel. This walkthrough shows you how to complete all of this nonlethal (without killing anyone) and undetected (without being seen or raising the alarm). I am also doing this without any upgrades, so I am not going to pick up any Bone Charms or Runes or any other loot since it is unnecessary.
