1974. A weekend in the port of Liverpool following a long sea exercise, six submariners hit the bars and hope to find some female company. A challenge is set for anyone who does strike lucky.
By the second pub, the clumsiness of Al becomes apparent. Here, Mike and Smiff con two barmaids into going on a date, the barmaids invite them to their club later that evening for a fancy dress party. Al is conned out of £25 by another girl.
They find some cut out Womble masks which they will wear for the fancy dress and 'personalize' them in another pub while having some friendly banter with two gays, especially Rich.
At a set off traffic lights Pete jumps into a sports car driven by a beautiful girl and the rest watch as the car drives off into the distance.
Later in the evening at the fancy dress and worse for drink, they begin to make fools of themselves which turns into a disaster with the barmaids and they decide to make themselves scarce.
Going onto The Grafton, they stop at a fish and chip shop, Lincoln meets up with a girl and helps her home.
Inside The Grafton Al is forced to dance, Mike is pestered by two drunken women and finally has an altercation with Smiff, getting them both thrown out.
Arriving back on board, they are surprised to find the Casanova's, Pete and Lincoln already there. They tell their tales of misfortune and then Rich enters. Has he won the challenge?
Much of the language and behavior was typical of seafarers at that time.
