This is a spin-off from the 1973 British television series Whatever Happened to the Likely Lads?, although it shares its title with the earlier series The Likely Lads, of which Whatever.. was the sequel. Terry is divorced from his German wife and has a Finnish girlfriend, Christina. At Thelma's suggestion they join her and Bob on a caravan holiday, but due to a mishap the men get separated from the women. Thelma mistakenly accuses Bob of infidelity, and their row is heard publicly as they are in a van with the PA still switched on. Bob and Terry then holiday without the girls in a hotel at Whitley Bay. They score with both the landlady and her daughter, but have to make a hurried trouserless exit. Terry decides to emigrate, and Bob joins him for a farewell drink on board his ship. However, Terry changes his mind at the last minute and disembarks - realising too late that Bob is still on board heading for Bahrain.
Bob and Terry find their lifelong friendship beginning to change as Terry becomes involved with a new woman. Bob is dismayed, but his wife sees the opportunity to get Terry married off and put a wedge between the friends.
