Martha Beck, an obese nurse who is desperately lonely, joins a "correspondence club" and finds a romantic pen pal in Ray Fernandez. Martha falls hard for Ray, and is intent on sticking with him even when she discovers he's a con man who seduces lonely single women, kills them and then takes their money. She poses as Ray's sister and joins Ray on a wild killing spree, fueled by her lingering concern that Ray will leave her for one of his marks.
Unfortunately the movie The Honeymoon Killers is not yet available on HBO Max.
