It feels like it’s been absolutely ages but this weekend, BBC One’s Casualty will return.

The medical drama has been off air since September, but will broadcast a brand-new mini series in a few days time.

The final instalment of the most recent boxset, Supply and Demand, saw the team at Holby City ED battle to save their friend and colleague Ngozi Okoye (Adesuwa Oni), who was rushed to hospital after relapsing.

Prior to this, Ngozi had said goodbye to her friends at Holby City Hospital to return to Lagos. Her young son Obi previously told Ngozi that he wasn’t happy in England anymore, and wanted to go home.

At the airport, Ngozi anxiously waited for her plane to get called. While this was happening, on/off girlfriend Nicole Piper (Sammy T Dobson) was chatting to Siobhan McKenzie (Melanie Hill). She had decided that she wanted to be with Ngozi after all, and needed to get to the airport before she left.

Siobhan raced Nicole across town, but a traffic jam outside the airport meant she was forced to run the rest of the way.

When Nicole arrived though, she found Obi on his own. In the toilets, Ngozi had fallen and hit her head after relapsing. Flashback scenes then confirmed Ngozi hid in the bathroom to try and miss the flight. After Nicole found her, Ngozi was rushed into the ED.

The instalment ended just as the team were continuing CPR on Ngozi.

This week’s episode will allow us to discover Ngozi’s fate, and meet some new members of the ED.

Here’s everything you need to know.
