Dante, Elias, and Jay and Silent Bob are enlisted by Randal after a heart attack to make a movie about the convenience store that started it all.
 
This movie feels like closure for Smith, but not for fans.  It's not a love letter to a franchise, it's a sad good-bye because the film is downer.
 
FUN FACT:  Originally, Kevin Smith announced in 2017 that Clerks 3 was off the table after a falling-out with his friend Jeff Anderson who had played Randall Graves in Clerks (1994) and Clerks II (2006). Anderson had read the script but chose not to be involved; Smith canceled the project and made Jay and Silent Bob Reboot (2019) instead. Two weeks before Jay and Silent Bob Reboot was released, however, Smith revealed that he had spent an entire day signing Clerks movie memorabilia together with Anderson and Jason Mewes (Jay). This reunion allowed them to patch things up, and provided him with so much inspiration that he immediately threw away the old script, and started working on a new one with ideas that Anderson was receptive to. According to Smith, it will be "a movie that concludes a saga [...] about how you're never too old to completely change your life [...] about how a decades-spanning friendship finally confronts the future."
