Who I am
Is not
A side effect.

Hearts and minds racing, Connie and Tristan are falling for each other fast. But is their sudden and intoxicating chemistry real, or a side effect of a new antidepressant?

As two young volunteers in a clinical drug trial, their illicit romance poses startling dilemmas for the supervising doctors.

Lucy Prebble’s (Succession) critically acclaimed play returns to the National Theatre in a bold new production directed by Jamie Lloyd (Cyrano de Bergerac).

Paapa Essiedu (I May Destroy You) is joined by Taylor Russell (Bones and All) in this funny and intimate examination of love and ethics.
