Lilith informs Frasier that she wants to spend a year away from him, sealed in a biosphere with her lover. Frasier reacts to this like any trained psychiatrist - he steps onto the ledge of Melville's and threatens to jump if Lilith leaves him. Lilith and Sam manage to talk him down, but Lilith insists their marriage is over. Once Lilith has gone, Frasier's friends rally round in support of him.

After returning to Boston only to discover Frasier in bed with Rebecca, Lilith comes to Cheers to seek Sam's advice. Frasier comes after her, and Rebecca shows up as well to explain. Frasier says he can't take Lilith back after what she did - just as her lover, Dr Pascal, shows up and takes the gang as hostages unless Lilith returns to him. When Paul and John Allen Hill show up and also get taken as hostages, Lilith has to persuade Pascal to let them all go, and that she doesn't want to go back. Plus will she reconcille with Frasier?
