Steam tells the stories of three very different women, whose lives are linked only by the steam room at the local gym. The women seem "stuck" in life. They are unable to overcome what is keeping them from growing and thriving in their lives, until each embarks on a relationship that will lead them to themselves.

Celebrated veteran actor Ruby Dee (American Gangster) plays Doris, a lonely widower who is in deep mourning for her husband. She has spurned her old church community, where once she sang and played piano. Unexpectedly, Doris finds a new love when she meets the outgoing August. But her new happiness is immediately threatened by August's family, who suspect her of being a gold digger.

Ally Sheedy (The Breakfast Club, High Art) plays Laurie, a "soccer mom" whose ex-husband has not only hooked up with a much younger women, but who is also shamelessly trying to turn their son against her. The bitter divorce and custody battle has very much dampened Laurie's spirits, but her life is revived when she gets involved with a much younger man. Chelsea Handler (The Chelsea Handler Show) plays Jacky, Laurie's best girlfriend, who comically encourages Laurie every step of the way in this risky relationship.

And Kate Siegel (The O.C.) plays Elizabeth, a college co-ed who is living on campus, but is still very much dominated by her strict parents, who live nearby and demand that she attend church with them every Sunday. In her Gender Studies class, Elizabeth meets and falls for the fiery activist Niala (Reshma Shetty of USA's Royal Pains). When the two women become lovers, Elizabeth must face her parent's wrath head on.
