If it wasn’t for that tiny detail, she would’ve been a terrific person

TV Guide’s summary of The Trainer, a Lifetime TV movie:

A recently divorced woman joins a gym and quickly becomes friends with Alex, a young trainer. Unfortunately, Alex is psychotic and a murderer.

Yes, that is quite unfortunate.

The official synopsis by Lifetime, also listed on IMDB, adds:

Sadly Alex is psychotic and has been murdering her trainees for years.

Very sad indeed. A slight flaw in Alex’s character.
