In the following clip, a doctor gives directions to a visitor who wants to find a particular ward.
The visitor complains that the directions are extremely difficult to follow "These signs are a nightmare." The doctor replies that the directions are a bit 'tricky' (difficult to understand) however the ward that the visitor wants to find is in the vicinity (near).
The expression "Dead easy" is used to mean extremely easy (to find)
The visitor then asks for directions back to the car park which the doctor gives her. The doctor ends the clip by saying "My pleasure" meaning that it was not a problem in the least to help.
