Sherlock Holmes and Joan Watson are back in action in Elementary season 4 episode 19 titled "All In." The episode opens with a prologue in which a poker player is found dead in a parking lot, his severed hand nearby. Taken as a warning from a rival player, the poker community is shaken, and it's up to Holmes and Watson to track down the killer.

As the detectives investigate the world of underground poker, they begin to unravel a complex web of deceit. They meet players from all walks of life, each with their own secrets and agendas. Tensions rise as they get closer to the truth, and the stakes get higher.

Meanwhile, Watson is dealing with her own personal issues. She's been avoiding her family since a recent blow-up, but her brother Oren unexpectedly shows up in New York. It's clear that the two have a troubled past, but Watson is forced to confront her demons and deal with her family's expectations.

As the case heats up, Holmes begins to put the pieces together. He realizes that the killer is using a unique technique to gain an advantage at the poker table, and that the motive is not what it seems. Along the way, he and Watson uncover corruption and betrayal among some of the players, and they must race against time to put the pieces together before the killer strikes again.
