Javier lives with Sonia, but he is having
an affair with Paula, who has just broken up with Pedro, Javier's
best friend. As these two couples, along with a collection of friends
and co-workers, switch back and forth between their lovers, their
lies escalate.

Copious lies lead on to endless deceptions, painful heartaches,
spontaneous couplings, and lots of song and dance. Bedfellows just
keep switching in this raucous and sexy romantic comedy with a musical
twist.

Part of the 2003 Sundance Film Series and a box office hit in Spain.
