The review discusses the physical program of a new experiment at the Super Charm-Tau factory, the basis of which will be a powerful electron—positron collider with a luminosity of ∼10³⁵cm^-2s^-1 and an energy in the center of mass system in the range from 3 to 5 GeV. A modern detector located around the beam collision point will provide a new level of measurement accuracy. The longitudinal polarization of the electron beam, along with record luminosity, will allow the unique experiment to successfully compete with the existing Super B-factories Belle II and LHCb. The extensive physical program includes the study of the properties and measurement of physical parameters of charmed hadrons, the τ-lepton, the charmonium, and exotic states, as well as the study of the production of light hadrons in e⁺e^--annihilation and in two-photon processes. In addition to testing the Standard Model and precisely measuring its parameters, a comprehensive search for New Physics beyond its boundaries is planned.
