It Ain't Half Hot Mum (1974)

S8E6 The Long Road Home

The Concert Party men are preparing to head back to Britain, and vaccinations are required before they leave. Unfortunately, Lofty misses out on his shots when the supply runs out, forcing him to remain behind as the others depart. Just as they leave, a new supply of vaccines arrives, allowing Lofty to finally get his injections. He sets off with the Char Wallah, determined to catch up with the main group during their evacuation.
