The Iron Ladies (2000)

Mon is good at volleyball, which is why he suspects his exclusion from the flagging local team has something to do with him being gay.
Then a new coach is appointed... Bee. She's a lesbian, with several championships to her name, and she wants to shake things up. The macho, self-appointed star player Muangman leads a walk-out in disgust, leaving Mon and his pal Jung the opportunity to offer their services and to help find a new team to play alongside them. When some of the new recruits turn out to be drag queens, Chai, the sole remaining straight player from the old line-up, has serious misgivings....
