FRIDA is the forthcoming imager and integral-field spectrograph for GTC that will deliver the highest posible angular resolution accessible today, from ground and space, in the near-IR, i.e., 25 to 40 mas in the 1 -- 2.5 um range. These angular resolutions are a factor fifteen improvement with respect to those of current and /or planned instruments for GTC, almost factor two superior than that of JWST. In this presentation, I will develop on science paths for FRIDA that illustrate the potential and unique capabilities of FRIDA at GTC.
