The Effect

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.

Jamie Lloyd (Cyrano de Bergerac) directs Lucy Prebble’s (Succession) funny and intimate examination of love and ethics.

Paapa Essiedu (I May Destroy You) plays Tristan and Taylor Russell (Bones and All) plays Connie.
