Los Angeles, 1931. On the heels of an unsavory investigation involving a famous comedian, Perry Mason--a PI struggling to make ends meet--and his right-hand man Pete Strickland are hired by attorney E.B. Jonathan, Perry's mentor, to solve a perplexing case: the brutal kidnapping of one-year-old Charlie Dodson, whose parents were targeted for a $100,000 ransom.

As Emily's trial begins and a damning witness testimony takes center stage, Mason attempts to recover from a shaky start. Meanwhile, in their search for clues that might lead to an exoneration, Della and Strickland investigate a potential connection between Detective Ennis and Charlie's kidnappers. Later, Mason considers betraying Drake's trust to give his client an edge.

Hoping to expose the hidden link between the Radiant Assembly's staggering debt and Charlie's ransom, Mason puts Herman Baggerly on the stand. Sister Alice faces mounting pressure from the church elders about her promises for a "resurrection." Strickland loses track of a key witness, while Drake's detective work opens a new avenue in the case.

After the team receives some unvarnished critique from Hamilton Burger, Della presents an increasingly stubborn Mason with her case for putting Emily on the stand. As the sensational trial winds to a close, Mason, Strickland, Della, and Drake attempt to tie up loose ends - and set the stage for their futures.
