Fellow Travelers is a decades-long chronicle of the risky, volatile and passionate relationship between charismatic, ambitious Hawk and pious, idealistic Tim -- two political staffers who fall in love during the height of the 1950s Lavender Scare. Their fiery affair endures through the Vietnam War protests of the 1960s, the drug-fueled disco era of the 1970s, and the AIDS crisis of the 1980s, all under the constant threat of exposure and losing everything.
