Plan from the position I am not asking for analysis, just want to know what are the plans to continue for black .(white to move)
A plan without (extensive) analysis can only be given in very stable structures. Here, the position is pretty tactical and volatile. White might be able to round up the e3-pawn with Nd1 and h3. Then black has to calculate hard to not wind up in a very bad endgame. 

So here my "plan" during a game would look like this: Use any tactical trick you can find to not lose the e3-pawn, and if you cannot avoid losing it, grab as much material for it as you can. 

Concretely, after 1.Nd1 Bf4 looks like a decent move. Then one "tricky" line would be: 1.Nd1 Bf4 2.g3 {2.h3 Bg3} Bb8 3.Kg2 {3.Nxe3 Ba7} Ba7 4.h3 Nf2 5.Nxe3 Nd3 6.Rd2 Nc1 hitting both rooks. 

All this depends on white playing the most obvious move, Nd1, but she might try to strengthen her position in any other way and then you have to come up with different tricks. What you might want to keep in mind is:


The bishop is happier on the a7-g1 diagonal.
The rook might want to invade the second rank or hit the a4-pawn.
The knight wants to jump around and fork things up. 
All considered: Active play is necessary.
