One Big Happy

In this comedy's premiere, platonic best friends Lizzy (Elisha Cuthbert) and Luke (Nick Zano) decide to have a baby, but when Luke falls in love, plans become a little complicated.

Prudence moves in with Luke and Lizzy and shakes things up. She also pushes Lizzy to clean out a closet of her ex's things, forcing Lizzy to deal with some feelings.

On a group trip to the gym, Lizzy spies her secret crush, Kate (ERINN HAYES), and Luke and Prudence help her initiate a conversation. Leisha helps Prudence explain her feelings.

Prudence convinces Luke and Lizzy that they need to spice up their lives. Fearing his new bride will find him boring, Luke takes a chance at skydiving - with disastrous results.

On a group trip to Las Vegas, Nick and Prudence discover that their hasty wedding was not legal, so Lizzy takes it upon herself to organize a spectacular new wedding.

After Luke learns about a secret that Prudence has been keeping from everyone, he disappears to hit the bars with Marcus, leaving Lizzy to pick up the pieces.
