With Sam now missing for a whole week, a terrified Tess enlists Abs’ help to scour the city looking for him. When a lorry loses control on a wasteland popular with homeless people and a young boy matching Sam’s description is found trapped and critical at the site, Tess fears the worst. Against Dixie’s orders, Greg risks his life to save the trapped boy – who turns out not to be Sam.

Abs finds Sam safe in a homeless refuge and persuades him to return to Tess, whose relief is short-lived when Sam tells her he’s going travelling in Thailand – and he’s leaving tonight. Tess agrees to let him go and sends him off with a smile. Realising that Sam won’t be around for much longer, Alice is forced to face up to her feelings for him. Can Alice tell Sam how she feels before it’s too late?

Selena and Nadia are given the unenviable task of treating Alex, the lorry driver involved in the crash. Obnoxious and sleazy throughout, Alex gives all the female staff a tough time so Maggie is pleasantly surprised when Stitch takes it upon himself to teach the sexist pig a lesson.

Also, a crash victim realises the importance of family when his surrogate son dies from his injuries; Tess treats a man who’s hiding his homosexuality; Greg becomes Dixie’s first choice for relocation after defying her orders at the crash site.
