Meet the Stallone Family: Sylvester, wife Jen, and their three daughters Sophia, Sistine, and Scarlet. Sly rejoins his family after months on the road shooting his new series Tulsa King. The girls plan to prank Sly on his birthday.

Scarlet can't wait to move away to college and embrace her independence, but Jennifer is having a hard time letting her last child go; Sly's TV shoot schedule forces him to miss a key moment in his daughter's life.

The family is concerned about Scarlet spiraling after a break up and call on Sly to get involved; Sly accompanies Frank to his big concert in Atlantic City and worries that Frank's habitual bad luck will derail the show.

Scarlet gets her first big break and heads to Oklahoma to act alongside Sly on his upcoming streaming series, Tusla King. After receiving pressure from their dad, Sistine and Sophia debate having their unfiltered Uncle Frank on their podcast.

As she gears up for her annual heart check-up, Sophia talks to Sly about the emotions surrounding her heart surgeries. Worried about his daughter's safety, Sly discourages Sistine from riding horses.

Sophia is worried that she will never live up to the success her parents have achieved and it starts to hurt her burgeoning literary career. Sistine finds success with her horror movie script, which causes a bit of sibling rivalry between her and Sophia.

Sly plans an emotional return to his childhood home of Philadelphia to show his children his humble roots. Scarlet embraces her newfound college independence and ditches the family trip... causing family turmoil.
