'Untouchable, Part One'

On his 21st birthday, a homeless youth called Owen searches for the meaning of life. At The Mill, Karen gives him a box of syringes and insulin as he is running low.

After tricking a pizza place to get free food, Owen's day progressively goes from bad to worse and he uses the insulin to give himself an overdose…

Meanwhile, Rose - a contract cleaner at The Mill - is late for her first day and Mrs Tembe has her in her bad books. Later, Rose isn't paid by her employer and is driven to desperate measures. She returns to The Mill to look for her cleaner's hat, but when she finds it, she pretends to continue the search and steals from the drugs cupboard. Will Mrs Tembe catch her?

Elsewhere, Karen and Rob bicker over whether they need a new sofa for the house.
