To make matters worse, Aiden will have to spend the weekend of the wedding with Max and his soon-to-be-husband at their lake house. So, rather than go alone, Max decides to invite his roommate's outrageous friend Lance to pose as his boyfriend. But, in the days leading up to the ceremony, Aiden discovers the awkward tension may be more than he can handle.
