No power to the GFCI at end of run
If you have NO Voltage on Line In at the GFCI - and I am talking the PHYSICAL WIRE and not the receptacle plug - then given you have power at the preceding receptacle and not at the GFCI - you have an OPEN circuit.

That means the wire is not feeding power due to a open connection or broken connection on the preceding receptacle or on the 1st GFCI. 


  Why you have the second GFCI I am not sure and ordinarily you would
  place the GFCI first in the line and all other circuits down line from
  the GFCI are protected no need for additional GFCI's in that circuit
  run.


I think there are also some issues with placing a secondary GFCI in line with an existing GFCI, either one or both GFCI's might not work properly.

If it is at the receptacle end where you are measuring no voltage - the GFCI has tripped. Given you have two at the end of the run - is the other one tripped ?
