Tess is terrified about Sam's wellbeing - he's been missing for a week with no sign. She enlists Abs's help and, together, they scour the city for him.

Meanwhile, Alice has also been worried about Sam's disappearance, so much so that Kelsey begins to work out her true feelings for him.

Elsewhere, at the site of an accident, Greg makes the heroic decision to enter a pit full of junk and save a trapped boy. However, in doing so, he defies Dixie's orders and puts himself in immense danger.

Casualty Show Summary

Casualty is the world's longest running and most successful medical drama series on television. It depicts the private and working lives of the patients, doctors, nurses and all others attending a small but frantically busy accident and emergency department of the large Holby General hospital. By mixing episodic plots with longer, character-based stories it ensures that we get to know the characters as people with lives, not just doctors or nurses. With consistently superb storylines and great acting, Casualty is compulsive viewing. The show began in 1986 and since then only one character remains; the one and only Charlie Fairhead played by Derek Thompson.
