Hetty Wainthropp Investigates (1996)

S1E1 The Bearded Lady

Hetty Wainthropp is frustrated by the birthday cards she receives for her sixtieth, all wishing her congratulations on "joining the club" of seniors, despite not being eligible for a pension. Refusing to let age define her, Hetty takes a position at the nearby post office. She quickly showcases her skills by ejecting a rowdy biker and pursuing a shoplifter, proving that she still has plenty of fight left in her.
