Max and Lou have made a promise to each other. For their wedding it will be only them and their witnesses. But that... That was without counting on the HUGE surprise party that awaits them! They wanted to be 4, they find themselves 300 and everything is going to get out of control very quickly... They were dreaming small, small... They will have big, VERY VERY big!
