In the series opener, Bo's impulsive decision to protect a young woman in jeopardy (Kenzi) has unexpected consequences: the two become fast friends, while Bo is swept up into the secret world of the Fae, learning for the first time about these ancient people and the birthright she never knew existed.

Fresh from the realization that she is a member of the Fae, Bo is approached by a strange client, Will, a real life Will O' the Wisp. The storehouse of jewels he's collected over the centuries has been stolen...by a human! While this line of work is foreign to Bo, Will offers her an irresistible payment - information about where she might have come from. As Bo gets involved in the recovery of Will's gems, she finds the shocking truth about the thief... and the weird and deadly forces that seem to also be on the trail of the jewels.

When a missing coed's mother comes begging for help, Bo and Kenzi go undercover on the local college campus to find her. Using all of Bo's unique talents and Kenzi's con artist skills, the women dig into the mysterious underbelly of the school's sorority system and find a surprising Fae connection, while racing to save the kidnapped young coed. On the personal side, Bo and Dyson enjoy the afterglow of their first sexual encounter, both wondering where it's leading them... until Trick's stern objections and Kenzi's excited pressuring threatens to put a rift between Bo and Dyson before they're even a couple.

When a Fury with an unfaithful spouse tries to hire Bo to kill her husband's mistress, Bo instead takes the side of the unsuspecting human woman and puts her under protection. Things quickly spin out of control, however, after the husband ends up brutally murdered, leaving Bo scrambling to contain a mess of jealousy and violence and unravel the mystery of the real killer – as Kenzi nearly becomes the next victim. Dyson has to submit to therapy at the cop shop when his romantic frustration over Bo causes anger issues, leading him and Bo to patch things up.

Bo is coerced into solving how a human scammed Mayer, a Dark Fae bookie. Things get creepy when she discovers the con artist behind it all is a Hsien, a Fae that can inhabit dead human corpses. Kenzi's determination to prove she's more than just the human "sidekick" leads her to do a little investigating on her own, which lands her in some serious hot water – and eventually, locked in the trunk of a car headed to a bad fate unless she can be rescued by Dyson.

While tagging after Lauren and Bo in the Fae world, Kenzi becomes deathly ill (and incredibly grossed-out) when she inadvertently eats some toxic human soup at the home of an Aswang - sending Bo and Lauren on a daring undercover mission in search of a cure, at a powerful pharmaceutical company. As Bo and Lauren race to save Kenzi, they are each forced to face their varying control issues – with surprising results – underscoring their growing attraction and the beginning of a possible relationship.
