Twins Blake and Bianca Dunlap have always been there for each other, ready to lend support and make sacrifices. Blake can't imagine a bigger sacrifice than getting along with Bianca's fiance, Matt. Matt turns out to be more than the meathead Blake had dismissed him as, but Matt's best friend, Ryan Everett, is a different story. Ryan seems intent on being an insufferable jerk as often as possible. The fact that Blake is undeniably attracted to Ryan only makes the whole situation more annoying. Blake is determined to make nice -- unfortunately he overshoots, and he and Ryan end up on much friendlier terms than Blake intended. As more complications arise, Blake and Ryan become more determined to do what it takes to avoid letting Matt and Bianca down.
