They're sworn enemies. They also happen to be incredibly attracted to one another.
After bonding at a half-marathon, rival gym owners Cam and Kailani discover the person they thought could be their soulmate turns out to be the reason their respective businesses are failing. When a heat-of-the-moment kiss leads to the pair becoming viral sensations, they pretend to be a couple to keep up interest despite the hatred they feel toward each other.
But new clients are not the only thing drawn in by the star-crossed lovers' fake relationship. They also grab the attention of a famous fitness mogul who tells them he wants to sponsor one of their gyms. The catch? One of them has to beat the other in a televised competition.
With undeniable attraction pulling the two together for real, Cam and Kailani agree to set their differences aside and enjoy the time they get to spend together while competing. Each new challenge becomes a chance for the two of them to get to know each other better, but their pasts keep getting in the way.
Unless they can learn to truly trust each other, not even a miracle can save a relationship that was doomed from the start.
