Lea Thompson ("Switched at Birth") returns as Paige’s (Katharine McPhee) mother in "This Is the Pits," as she gives Ralph (Riley B. Smith) a boost with his cookie sales — unbeknownst to Paige. On a more urgent note, the team tries to rescue a trapped woman from Los Angeles’ La Brea Tar Pits before she suffocates. Elyes Gabel, Robert Patrick, Eddie Kaye Thomas, Jadyn Wong and Ari Stidham also star.
