The icon shows Jesus, vested in white and gold to symbolize his divine majesty, standing on the brazen gates of Hades (also called the "Doors of Death"), which are broken and have fallen in the form of a cross, illustrating the belief that by his death on the cross, Jesus trampled down death (see Paschal troparion). He is holding Adam and Eve and pulling them up out of Hades. Traditionally, he is not shown holding them by the hands, but by their wrists, to illustrate the theological teaching that mankind could not pull himself out of his ancestral sin, but that it could come about only by the work (energia) of God. Jesus is surrounded by various righteous figures from the Old Testament (Abraham, David, etc.); the bottom of the icon depicts Hades as a chasm of darkness, often with various pieces of broken locks and chains strewn about. Quite frequently, one or two figures are shown in the darkness, bound in chains, who are generally identified as personifications of Death and/or the Devil.
Some icon. Beautiful! I love that style.
