Signed, Sealed, Delivered

The film begins in the Dead Letter Office (DLO) in Denver, where the team—Oliver, Shane, Rita, and Norman—receives a long-lost box of letters from a decade prior. Among them is a 'NIFTS' (Not Intended For The System) letter addressed to a 'Pastor Thomas.' The letter is a desperate plea from a mother who cannot afford medical care for her son Joshua's heart condition, quoting Jeremiah 29:11. The team tracks down the late Pastor Thomas's son, Jim, who reveals he found the abandoned baby 32 years ago. This leads them to Joshua Davis, a cold and professional cardio-thoracic surgeon who harbors deep resentment toward the mother he believes 'threw him away.' Parallel to the investigation, Norman Dorman reveals his own history as a foster child who was found as a toddler after starting a stampede in a cattle paddock. Encouraged by Shane, he opens a letter from the national adoption registry and discovers he has a grandmother, Ardis Parker-Pennington-Paine. Ardis arrives in a whirlwind of eccentricity, having just flown in from Papua New Guinea. She is a flamboyant traveler who drinks yak milk and takes Norman on bizarre sightseeing trips to 'Tiny Town' and a toxic waste park. While researching Joshua, Rita uses her photographic memory to identify his face in a sports magazine, but under a different name: Matt Jacobs. The team realizes Joshua has a twin brother who was not given up for adoption. They locate Matt and his mother, who explains she was a terrified 19-year-old who gave up one twin only so he could receive the expensive heart surgery required to survive. The story reaches a climax when Ardis suffers a heart attack and is coincidentally treated by Joshua. From her hospital bed, Ardis uses her eccentric charm and a bizarre story about circus clowns in Singapore to manipulate Joshua into meeting his mother and brother. The families are finally reunited in the hospital. In the resolution, Norman finds peace with his own past, learning about his 'sparkly' mother from Ardis and gifting Rita a stuffed crab to remind her she is 'unsquashable.' Oliver, meanwhile, continues to struggle with a letter he has written to his estranged wife, Holly, who is living in Paris, leaving his romantic future with Shane in a state of 'will-they-won't-they' tension.
