Ian Carmichael "Willie", is the pretty hapless son in a family of petty thieves. One evening he turns up at their daily reckoning with a suitcase that he pinched from a vicar at the railway station. Turns out it contains a small fortune in £1 notes. Snag is, they all have the same serial numbers. Prudent dad (James Hayter) tells him to burn the lot, but he refuses and armed with his loot, he sets off to make a living on his own. Meantime, Robert Helpmann is trying to find out who stole his cash - and is soon on his trail. Carmichael tries quite hard here, but the joke runs out of steam very quickly and the comedy becomes more thinly stretched as he tries to impress barmaid "Gloria" (Brenda Lee). Kathleen Harrison hams up nicely as his emotionally charged mother, and Leslie Philips manages to get in on the joke renting him out an hotel suite for 40 guineas a day, but these are but fragments in a lacklustre vehicle for a star that is just short of sustainability.
