Ross Fableton, an extroverted, confident, but hypercritical college student (22), wants nothing to do with his new, introverted, and standoffish stepbrother Ryan (20), and the feeling is mutual. When their parents go on vacation in an attempt to force the stepbrothers to interact, Ross and Ryan's sniping and pettiness reaches a boiling point - just as robbers break into the house. If Ross and Ryan can't overcome their sibling rivalry to try take down the robbers, this dangerous situation could have fatal consequences.
