Returning home from the cinema Lucy and Lee are mugged. Lucy feels Lee could have been more heroic so he joins a gym to learn boxing but in his first fight he is beaten by a little girl. He hopes to impress Lucy by doing a deal with the robbers but this does not work out. However his visit to the gym does - albeit in a roundabout way.
Envious of their interesting life style Lucy befriends Anna and Toby though Lee feels left out so Daisy suggests he invites then to a dinner party . This he does, pretending to be a successful business man with tickets for an upcoming charity event. Feeling sorry for him - and admitting to being hen-pecked - Toby gets the tickets for him and allows Lee to take the credit. Unfortunately at the charity dinner Lee gets very drunk and the lie is exposed but when he takes to the stage to sing Lucy's praises and Anna criticizes him Lucy realizes which of the two's friendship means the more to her.
Lee's dad, Frank, takes Lee on his stag night the night before Lee and Lucy's wedding, which causes some serious problems for the pair and Lucy's dad, Geoffrey, the following morning. Will the three men make it to the wedding on time?
Lee and, a heavily pregnant, Lucy are out doing some last-minute Christmas shopping on Christmas Eve when they get caught up in a robbery in a department store.
