Official trailer for Stan's original drama 'Bloom' reveals the power of mysterious plant

After two mysterious teasers, Stan has finally unveiled the full trailer for its upcoming original drama Bloom.

In Bloom, an Australian town is ravaged by a devastating flood that claims the lives of five locals.

A year later, a suspicious plant is discovered in Gwen and Ray Reed's backyard. When their ageing dog eats it, Ray thinks it'll die. Instead, their dog is restored to its former puppy self -- which makes them realise that the plant will give them a second chance at youth.

Gwen, who suffers from Alzeihmer's and has been moved to a care facility, consumes the plant, and immediately becomes her younger self.

The characters are then forced to re-evaluate what's important in their lives.

Bloom includes an all-star Australian cast including Jacki Weaver and Phoebe Tonkin in the roles of Gwen, Bryan Brown as Gwen's husband Ray, and Ryan Corr as Sam, a mysterious young man who arrives in town and seems to know Gwen and Ray's secret.

Watch the trailer above.

All six episodes of Bloom will be available to stream on Stan on January 1.
