Joan and Fred plan to sail away to a wonderful new life together, but Fred's arrest for murder casts something of a cloud over their dreams.
Meanwhile, Del has fallen in lust again, and the lucky girl's parents throw an engagement party they will never forget.

It is Christmas, 1960, and Cupid's little arrows are flying through the wintery skies over Peckham. Fred is in love with his new charlady; Joan is in love with her new baby, Rodney; and Del is about to get engaged three times in the same week.

Peckham, 1960, and the Trotters are all under one roof: Grandad, Joan, husband Reg and the teenage Del Boy. Things suddenly change, however, when ex-con Freddie Robdal appears. Joining this comedy drama are teenage versions of Only Fools and Horses favourites Boycie, Trigger and Denzil.
