STAGE TUBE: Sneak Peek - Season Finales of Showtime's SHAMELESS, HOUSE OF LIES, CALIFORNICATION, 4/1

Prepare for one rip-roaring, rollicking night of season finales on Sunday, April 1st on SHOWTIME with SHAMELESS (9 PM) and HOUSE OF LIES (10 PM) and CALIFORNICATION (10:30 PM).

First up on SHAMELESS, Frank (William H. Macy) enlists Debbie (Emma Kenney) and fellow inmate Jill (guest star Jenna Elfman) to break Monica (guest star Chloe Webb) out of the psych ward; Fiona (Emmy Rossum) finally meets Steve/Jimmy's (Justin Chatwin) family; and Ian's (Cameron Monaghan) fling with the mysterious Ned (guest star Harry Hamlin) is sure to shake things up in a major way.

Meanwhile, on HOUSE OF LIES, the Pod's - led by Marty (Don Cheadle) - 9th-hour attempt to dismantle the pending merger ends in a jaw-dropping confession. And on CALIFORNICATION, the Santa Monica Cop filming ends with a bang. But just when Hank (David Duchovny) thinks he's dodged a bullet, one blast from the past appears in his dreams and another in his nightmares.

The season finales will air on Sunday April 1 beginning at 9:00 pm/et.
