In 1960, Eli (Ayres) and Penny (Durance) take in Eli's curmudgeonly father, Walter (Serge Houde), and are forced to navigate some tricky family waters to get through the holidays while also working on a Christmas themed time capsule for son Alex's school project. In 1998, we see Regina (Bell) and Nelson's (Denton) first meeting: stuck together when a blizzard strands Nelson in Regina's home on Christmas Eve. In 2015, Jessie (Gonazlo) faces a big challenge while planning her sister's last-minute Christmas Eve wedding - the officiant is Tim (Rottman), her high school sweetheart, whom she hasn't seen in almost 20 years.
