Percy is taking some trucks to Brendam Docks when Terence tells him "it's a nice day for it." Percy is confused as to what "it" is, to which Terence replies by telling him Mrs. Kyndley's daughter is getting married today which he remembers and continues on his way. Further up the line, Mrs. Kyndley waves him down. When Percy's driver asks her what is wrong, Mrs. Kyndley says she has forgotten the good luck package for the wedding. Percy, confused, asks what it is, and Mrs. Kyndley says it contains "something old, something new, something borrowed and something blue." She then asks if they can help, and Percy's driver states they will see what they can do.
At Wellsworth, Percy stops to take on water and asks Edward about the good luck package and how to find it. Edward says they may be closer than Percy thinks and leaves to pick up the guests for the wedding.
Arriving at the docks, Percy looks around and finds a new set of buffers on a flatbed, saying it fits as "something new." His driver speaks with the Foreman, who lets them use it as well as borrow the flatbed, satisfying the criteria in "something new" and "something borrowed" for the package. Percy takes them and his trucks to Tidmouth Hault, where while shunting his train into a siding, he finds Old Slow Coach, who he and Thomas saved from being scrapped, and uses her for the "something old" object. Now only needing "something blue," Percy questions where he can find it and finally meets a ribbon-adorned Thomas as the "something blue" in the Fishing Village, where the wedding will take place. With the package complete, Percy's driver reveals to Percy that Mrs. Kyndley has chosen him to be her special guest, much to his joy.
At the church, the bride and groom leave for the reception just as the engines arrive. The Fat Controller announces the Good Luck Package, all found by Percy and his crew. The delighted bride thanks the engines and even kisses Percy, much to Thomas' mirth as Percy blushes. Later that night, Percy declares he loves weddings while Thomas cheekily asks if he enjoyed his kiss. Embarrassed, Percy closes his eyes and pretends he is asleep.
