Darrin cannot understand why so much bad luck has befallen his friend Adam Newlarkin (William Redfield). Doing a bit of research on her own, Samantha discovers that the accident-prone Adam is plagued by an ancient curse. With the "help" of dotty old Aunt Clara, Sam tries to lift the curse by following a strict -- and very odd -- antidotal procedure. Written by Bernard Slade, "We're in for a Bad Spell" originally aired on September 30, 1965. ~ Hal Erickson, Rovi
