Ben and Maddie (Alex Roe, Fola Evans-Akingbola) reluctantly attend a fundraising gala thrown by his mother, where a very unexpected guest shows up and offers to do whatever it takes to put an end to the overfishing that is threatening the very lives of the mermaids in the waters of Bristol Cove. Eline Powell and Ian Verdun also star in the new episode “Showdown.”

Michael (J.J. Totah) has high hopes of his musical being chosen to be performed as the freshman show in the new episode “Nepotism.” Vince (Anders Holm) is given reason to wonder if he gives preferential treatment to some of the gym’s employees.

The drama returns for a less-serialized third season, with Priyanka Chopra resuming the role of espionage agent Alex Parrish as the saga picks up with “The Conscience Code” — a while after the point where Season 2 ended. Three years later, she’s separated from fellow operative Ryan (Jake McLaughlin) and living abroad incognito, but she gets back into the spy game. Oscar winner Marlee Matlin, pictured, joins the series as a former FBI agent who also returns to duty.
