After spending several holidays away from the family, Dean is thrilled to be reunited with them for his first real Thanksgiving celebration in a long time. But his overexcitement and meddling brings a major, unexpected family secret to light. Meanwhile, a series of flashbacks reveal the chain of events that led to Dean's departure from his hit TV drama.

“The Grinder: New Orleans” -- a spinoff of the original hit series, asks Dean to film a scene giving closure to his beloved character, Mitch Grinder. Not surprisingly, Dean struggles with being replaced by his TV brother, Rake. Meanwhile Stewart, who has also been feeling replaced by his brother in Ethan's eyes, jumps at the opportunity to get Dean back into acting and out of his hair.

As the conspiracy surrounding Sanderson & Yao reaches a boiling point, the only man who can get to the bottom of it has abandoned the "grind" and enrolled in law school. Stewart, desperate for Dean's help, will go to any lengths to turn his brother back into "The Grinder".

Post-therapy, Dean finds that he has lost the ability to grind. To get it back, he decides to crack the case of the office being ransacked. Meanwhile, in flashback, we see a younger, struggling Dean Sanderson as he must decide whether to embrace a simple life, or pursue his destiny and become the Grinder he was always meant to be.
