Over the holidays, three couples at different stages of their lives traverse significant life turning moments at 7 Cherry Lane.

Three families at different times — a wartime doctor and his wife in 1951, a newlywed couple and their in-laws in 2003, and a new couple in 2024 — experience their own unique Christmas Eves in the same house at 7 Cherry Lane, all connected by their efforts to preserve the spirit of Christmas and create special holiday moments.

In 1960, a family works on a time capsule while hosting a grumpy grandfather; in 1998, a blizzard brings two strangers together on Christmas Eve; and in 2015, a wedding planner is reunited with her ex-boyfriend, who is officiating her sister's last-minute Christmas Eve wedding.
