In the Company of Men (1997) plot summary
Chad, a cold-hearted, sexist pig, has recently been dumped by his girlfriend Suzanne. His friend, Howie, is also having relationship troubles. Chad then comes up with a plan to satisfy their hate towards women; find a vulnerable woman with low self-esteem, date her for six weeks, and then dump her like she's never been dumped before. Howie agrees to the plan, though very reluctantly. Chad finds a worthy target in Christine, a beautiful, deaf secretary with a heart of gold. While Chad coldly slimes his way into her heart, Howie finds himself honestly falling in love with her, and finds himself changing his mind about the plan.
