Jack Clooney is a twenty-something aspiring writer, who is in love with Allison Blake, the beautiful, adventurous woman who has captured his heart. One evening Allison goes out with her friends and doesn't come home until the next morning. Afterward she tells a heartbroken Jack that she needs space.

Jack desperately wants Allison back, but he doesn't know how. He must decide whether he wants to be the man he's always yearned to be, or whether he should continue hanging out with his juvenile friends. Jack solicits the help of his happy-go-lucky brother Kevin, and best friend Annie, to try to win Allison's heart again. As all three friends become immersed in self-destructive mischief, Jack soon realizes that his chances redemption are quickly diminishing. Kevin's attention is diverted away from his quest for true love by plans for a Bigfoot-Sighting Party, and he tries to recruit someone crazy enough to dress up in a Bigfoot costume and scare the partygoers.

Mad Season will take you on a twisting, turning, arms-in-the-air roller coaster ride through the insane life of Jack Clooney, who must deal with a loveable, very hairy, eight-foot Yeti who may be the only living thing who can help heal his broken heart.
