For her role in Raw, McKenna stripped naked for a full frontal scene in the fourth episode. The Actress was pleased with the lack of complaints about the scene, apparently considering it an indication of the growing tolerance of Irish audiences. Scenes involving restaurant staff tampering with their guests' food similarly failed to attract much complaint. McKenna's character in the series is Jojo, a young chef, working under Tanya, a stressed manager, and a head chef. In the second episode, Jojo organises a party but the alcohol runs out and tensions rise. Raw, a six-part series set in a fictitious restaurant in Dublin, saw McKenna interact with Bachelors Walk actor Keith McErlean and Mistresses Actress Shelley Conn. McKenna departed RAW following the Season 5 finale on 10 February 2013.
