An intelligent, eccentric high school senior devotes his life to indulging the every whim of the beautiful girl he adores in this quirky, dark-humored comedy. Roddy McDowall plays Alan Musgrave, an odd duck who immediately falls for the school's new student, Barbara Ann Greene (Tuesday Weld). Using his quick wits, he helps her win acceptance amongst the popular girls and a cushy job in the principal's office. Never demanding anything in return, Alan doesn't even complain when she falls for an upper-class college boy, and he does everything he can to bring the two together. However, as time passes, this seemingly well-intentioned dedication spins out of control, with results that become increasingly bizarre and even potentially fatal. The irreverent attitude and erratic tone may be an acquired taste, but the film's audacious humor and idiosyncratic approach have won it a cult following.
