No Surrender is a 1985 British comedy film written by Alan Bleasdale, directed by Peter Smith and produced by Mamoun Hassan.
The hall has been simultaneously booked by rival groups of militant Catholics and Protestants, the entertainers hired for the night are inept and their acts are likely to infuriate the clients, and a marching band of the Orange Order starts playing sectarian tunes.
On New Year's Eve in Liverpool, Michael becomes the new manager of the Charleston Club, a run-down function hall on an industrial waste ground which, he later discovers, is owned by an organised crime syndicate.
He also discovers that the previous manager, MacArthur, in an attempt to spite the hall's owners, has hired it out to two groups of senior citizens for New Year's Eve; one group are hardline Catholics and the other are hardline Protestants, and the entertainment consists of a magician with stage fright, a gay comedian and his boyfriend, a talentless punk band, and a fancy dress competition with a non-existent prize.
After discovering MacArthur being tortured in a back room by the hall's owners, Michael, along with bouncer Bernard and kitchen porter Cheryl, attempts to keep things in order amid the threat of violence in the air.
