Series 32 is the thirty-second series of Casualty and commenced airing on 19 August 2017. Filming for the series' first episode began in April 2017. The series contains 44 episodes, the same as the previous series.
The series opened with a two-parter special, set partly in Holby and partly in France. Despite this, filming for the France scenes took place in Wales.
This was the first series of Casualty not to have episode names for its episodes. This was later revealed to be because coming up with episode titles was "incredibly difficult" and made the show feel dated. The episode titles during production were known for episodes one, two, five and six of the series, but like the other episodes in the series, they were scrapped when the episodes aired.
Dylan, David, Louise and Alicia set off to Calais to offer medical assistance at a refugee camp. There, Alicia takes a shine to British medic Cameron Hamilton, who has been on the scene for a while, helping the camp's women and children.

Naturally, Robyn has a few questions, and Dylan fills in the blanks by flashing back to the morning after Charlie's stag do, when he found a depressed Glen drinking away his woes in a rough karaoke bar. Determined to convince him not to give up on life, Dylan enlists the aid of his feisty old university tutor Zsa Zsa Harper-Jenkinson - an eminent brain surgeon in the US - to assess Glen's case.
