XL tells of the adventures of party-hound, boozer, womanizer and Senator, LEIF SIGURDARSON (Ólafur Darri), who is ordered to go into rehab by his friend and colleague, the PRIME MINISTER (Thorsteinn Bachmann). But before Leif is committed, he throws a party for his dearest ones, including his business partner ERIK (Helgi Björnsson), his lawyer CHRISTINA (Elma Lísa Gunnarsdóttir) and his young lover (and daughter's best friend), ÆSA (Maria Birta). As the party progresses we learn more about Leifur's past and his relationships and we discover not only a man's dark secrets but a Nation in identity crisis.
