When Syd applies for a grant for her clinic from a prestigious medical foundation, she meets a mysterious man who claims to be her father -- and as she gets to know him, his story about his relationship with her late mother begins to make more and more sense. Meanwhile, as Jim senses that Syd and Joanie are snooping around about the circumstances of Syd's birth, he treats a Lhasa apso dog that refuses to eat. Elsewhere, Robbie gets heat from the ex-husband just when it seems his romance seems to be blossoming with the attractive mother of one of his pee-wee hockey players and Joanie reluctantly hires a sensitive, temperamental baker.
