It's Christmastime again, and the team is on the verge of a breakthrough. Anthony Partridge has been working nonstop to finish his latest invention, and though he's made substantial gains, he may stand to lose even more. Jack Wyatt is done with the whole ODAR game and wants to take his girlfriend Penny with him, but Esther's just stuck one foot further in and might need his help. And Sally, all alone on Christmas, finds solace—and the answers she's been looking for—in her new 20th-century family. But with Bill Donovan in dire straits and Anthony Partridge left all alone, who knows what discoveries yet lay hidden?
