MMA trainer Sienna Lane (Kiana Madeira) appears to have it all: a promising career in mixed martial arts and a loving relationship with Jax (Matthew Noszka), a reigning MMA champion. But her perfect world shatters when she rushes home early one day to find Jax in bed—…with her own sister, Beth. Devastated and betrayed, Sienna must rebuild her life from scratch.

Determined to exact revenge rather than dissolve into heartbreak, Sienna sets her sights on training Jax’s fiercest rival—Kayden (Ross Butler), a brooding underground fighter with his own demons. What begins as a calculated pact—training him in exchange for a place to stay—soon blurs the boundaries between coach and confidante, sparking a fierce, passionate connection neither anticipated.

As Sienna tutors Kayden for the fight of his life, she also reclaims her strength, ambition, and soul. Through sweaty training montages and simmering chemistry, revenge morphs into something deeper—rekindling her sense of self and opening the door to unexpected love with someone who truly sees her worth.

With dynamic fight choreography, a richly diverse cast, and a heroine who transforms revenge into empowerment, Perfect Addiction delivers a compelling blend of sports, romance, and redemption that hooks audiences from the first punch.
