Have to be careful here,have a new sump plug ready and washer,get you and a mate to get 2 cold chisels in good condition,2lb hammers and strike the plug at 180 gegrees to each other,obviously going a/clockwise,try and synchronise hitting edge of plug at the same time and shock it loose,once it is moving should come off ok but watch the sump!
