Earth: Final Conflict (1997)

S2E17 Bliss

Lili falls victim to a dangerously addictive substance known as Bliss. Meanwhile, Liam and Sandoval travel to Ireland to trace its roots, where they encounter Dr. Cox and a group called the "Taelonists," who claim to know nothing about the drug. As they dig deeper, they stumble upon a lab where Ma'el had been developing a cure for Bliss, leading them to suspect that the Taelonists have discovered the facility and are now distributing the drug.
