A new true crime offering is resurfacing the decades-long “Monster of Green Hollow” mystery, the investigation of a rumored serial killer believed to have murdered dozens of women including three of his wives. Streaming on Paramount+ on Tuesday, April 28, at 12 a.m. PT/3 a.m. ET, the three-part docuseries, My Killer Father: The Green Hollow Murders, aims to unmask the alleged killer, Donald Dean Studey, after one of his now adult-aged children says she was forced to help bury bodies on their property.

While Paramount+ plans start at $8.99 per month, there’s a workaround to watch the limited series for free: Sign up for a five-day trial period to one of DirecTV’s signature packages — Entertainment, Choice or Ultimate — which offers the first three months of Paramount+ included at no extra cost.

How to Get Paramount+ Free Trial, Best Streaming Deals

When signing up directly through the streaming service, Paramount+ plans start at $8.99 per month. There are also two little-known workarounds to get Paramount+ for free through partner subscriptions, DirecTV and Walmart+.

Starting off with DirecTV, customers who sign up for one of the streaming service’s signature packages — Entertainment, Choice or Ultimate — will get the first three months of Paramount+ Premium included (see here for more details on these premium add-ons). Plus, DirecTV offers a five-day free trial for any plan, meaning new members can stream Paramount+ (and everything else the packages have to offer) at no cost during the trial period.

As for the other option, streamers can get free Paramount+ access through a Walmart+ membership, which includes the choice of Paramount+ Essential or Peacock Premium in its subscription. And since Walmart+ offers a 30-day free trial, members can stream Paramount+ at no cost during that period. Learn more about Walmart+ streaming offers and pricing here.
