If you loved Making a Murderer then you will probably love this.

New Netflix true crime documentary Dream/Killer was released on the streaming service yesterday (November 20) and tackles the tale of a father battling against the American justice system in an effort to get his son Ryan free, with him having been jailed for a murder he claims he was not responsible for.

The film follows the 2001 murder of a man named Kent Heitholt who had been strangled to death with his own belt and left in a car park at his workplace.

Unsolved for two years, the case took a turn when police received an anonymous tip-off about a man named Charles "Chuck" Erickson, who attended multiple Halloween parties on the night of Heitholt's murder and was taking drugs when he met his friend Ryan Ferguson at 10.30pm that evening.

Erickson said he was unsure if it was a memory or a dream when he thought of killing Heitholt, but his statements incriminated him and Ryan in a police interview.

Ryan was adamant he had no idea what had happened, but police told him that Chuck had given them vital information that the press did not know.

Chuck was charged with murder in the second degree, while Ryan was charged with murder in the first degree.

At the age of 20, Ryan stood trial, with the main evidence against him being Erickson's testimony of memories that came to him after speaking with police.

When Ryan's dad began his own investigations, he found various roadblocks, but then that all changed.

However, Ryan eventually found his way to freedom - but how ?

Enter Making a Murderer lawyer Kathleen Zellner. But how do they win?

Dream/Killer is available on Netflix now.
