What happens with the 2nd mortgage when I give the 1st mortgage holder a deed in lieu of foreclosure?

I am unemployed and cannot pay the mortgage payments. I have the home on the market but it will not sell for the loan amount. I was thinking of giving the 1st mortgage holder (80%), a deed in lieu of foreclosure. Will the second mortgage holder (20%) be able to get any money or be able to file a judgment against me as home owner? I live in the State of Arkansas.
