Submillimeter galaxies (SMGs) at z > 4 have been proposed as likely progenitors of the massive and compact population of quiescent galaxies at z ~ 2, that eventually evolve into the massive local ellipticals. In this context we have assembled a unique sample of 6 spectroscopically confirmed z > 4 SMGs and followed them up with high-resolution multiband HST and ALMA line and continuum observations. From the resolved rest-frame UV and FIR imaging, we have been able to unveil the morphologies, and fully characterise the star formation, and dust attenuation processes in these sources. At the same time, line observations have allowed us to describe the kinematics of the star formation. Together, we have uncovered the origin of these sources in the IRX/beta plane, constrained their stellar and dynamical masses, revealing a minor merger nature from the stars, extreme rotation from the gas, and set a much clearer evolutionary path towards the z~2 quiescent galaxies from unambiguously determined dust sizes and accurate stellar masses.
